Butterfly: How an extremely small event, like deciding not to buy a newspaper, could lead to thermonuclear war.
If I Ruled The World: Could a benevolent dictator keep control of the world and end up doing more good than harm in the long run.
Read the 1st sentence of your Tower idea, thought,“I MUST watch that!” I hate your 2nd move (JMHO), your 3rd is awesome.
I have an idea, but nobody wants to hear about it. 
Wipe Out: Intelligence services in China, Russia and the U.S. are locked out of their computer systems for some unknown reason, at first thinking that one(or both) of the other two countries is/are responsible things get tense, but when that possibility is eliminated they work together(or, most likely, pretend to) to find out what happened and fix the problem if possible. Possibility of large all-star cast playing agents of the different countries.
I’ve had a number of ideas I thought would make good movies. In fact, at least one of them – an adaptation of Sławomir Rawicz’s questionable real-life story The Long Walk – actually made it to the screen back in 2010 as The Way Back. Unfortunately, despite a big budget and Oscar-bait credentials, the flim slipped quietly in and out of theaters. So what do I know?
Also, this is not an original story but I’ve always thought the French film duology Jean de Floretteand Manon of the Spring could be remade as a Western. Instead of being set in Provence during the 1920s, the Americanized story would take place in the Texas Hill Country a decade after the Civil War. The César-character (played by Yves Montand in the films) would be a greedy cattle rancher while the hapless hunchbacked farmer Jean (Gérard Depardieu) would instead be a crippled Union veteran who inherits the land the spring is on. Larry McMurtry could adapt the story for the screenplay. (I would not be surprised if this hasn’t been already pitched in Hollywood sometime over the last 25 years.)
Out with it. Hollywood is no place to be meek.
I’ll go ahead and share some more movie ideas I have:
5/16: Loose Change from an alternate universe. If you’ve seen Loose Change, you know the engaging way in which the filmmakers tell their story; step by step, they bring up a facet of what happened on 9/11, and then after each step they tell us what really happened (“on 9/11 the government tells us terrorists hijacked 4 planes- but what really happened was the planes landed in Cleveland and the government flew drones into the targets”, etc.).
Imagine an alternate universe in which the U.S. was attacked on May 16th, 2001, not September 11th, and the attack was much more complex and wild than even 9/11 was. Now imagine that a group of young filmmakers in this alternate world made a Loose Change-type documentary about what really happened on 5/16. Then imagine you (in this universe) watched their documentary. As you sat and watched, the filmmakers would proceed step by step to tell you what supposedly happened on 5/16, and step-by step tell you what really happened on 5/16 (example: “on 5/16 the government tells us Wrigley Field was gassed by Iranian and Pakistani terrorists- but what really happened was the US government hired Chinese nationals to escort all the spectators into an underground cavern and then filled the stadium with prosthetic human dummies and harmless water vapors”).
As you watch, you get two great stories you’ve never heard, the story of what supposedly happened on 5/16 (which you have never heard, since you live in this universe not theirs) and the story of what really happened (so the filmmakers claim). Quite a mind-bending experience, no?
Unlike Loose Change, 5/16 has cinematic production values, special effects, and dramatic reenactments of the events.
A little sick, but hey, so’s Saw.
Christ! The True Story: I think the world is ready for a big-screen highly irreverent telling of the gospel story of the life of Jesus Christ. Sure, Life of Brian did something similar 30 years ago, but Python’s film wasn’t about Christ really it was about a Christ-type guy named Brian. Plus, Christ! The True Story contains material you wouldn’t believe (scatological, sexual, anachronistic pop references, swearing, et al).
Maybe I could get Mel Gibson to fund it…
Last Man on Earth: Comedy about a moron who thinks he’s survived an apocalypse and is the last man on earth, but really everyone else is still there and nothing bad happened, he just doesn’t realize it because of a series of misunderstandings and because he’s a moron who’s seen Mad Max one too many times.
Pulling Cable: ‘Pulling cable’ is a film industry term for lugging cables and equipment around a movie set, something the grunts do during a film production; but in the title of this dark comedy, it takes on new meaning, as in ‘Yanking cables out of a production to sabotage it.’ Two guys who are tired of pulling cable on other guys’ films and realize they’ll never be a director themselves decide to leave the industry, but before they do they join the production of one last movie, some overblown vapid 500 million production by a talentless Michael Bay-type director, just so they can sabotage the production in every way possible. I’ll let you imagine all the ways they attempt to do this.
Outer Space Ocean Movie: Great title, huh? Not really, it’s not a real title yet, just a description of a good 3D family adventure film about a group of astronauts who fly to another planet so they can explore the ocean on that planet. There’s almost no mention in other-planet/alien movies about what the ocean might be like on that planet/alien world, so I think it’s an original idea. Tons of weird stuff happens, storms and creatures and underwater civilizations and volcanoes and such.
Trivial: dark comedy about a man who will do anything to win on a trivia game show, ala Jeopardy!
Knox Gold: Three guys attempt to steal the gold at Fort Knox, but find out it’s really buried under the Meade County Bank in Muldraugh, Kentucky (a small town located on the Fort; the bank there is designed in real life to look like the bullion depository building on Fort Knox), so they steal it.
OK Wrecking Ball, you asked for it! 
A lesbian couple meet at college, and become friends with a gay couple while in graduate school. Their respective children eventually marry and raise their own kids. The MC daughter befriends a woman in wheelchair at college, the friend goes on to compete at the Paralympics.
I would totally watch that.
I had an idea about an evil dog that shoots bees out of its mouth.
Or maybe that was an episode of The Simpsons?
The Aspect of Loki: an advanced AI becomes many times more intelligent than human beings, figures out how to talk to other very advanced AIs in the universe, and develops techology millions of years beyond anything human beings have. The AI has little or no interest in human beings at this point, we being like unto ants to it, but he does set up a subroutine of more limited intelligence (but still much smarter than humans) called LOKI to protect the human race and try to get them moving in directions that leave them and their planet healthier and happier. LOKI thinks about it and then gives a struggling standup comedian what amounts to super powers via advanced tech, and charges him (or her) with figuring out how to move the human race along without turning all humans into lotus eaters or automatons, etc. The story involves how the standup comedian (who is the Aspect of Loki) goes about that.
Probably work better as a TV series than a movie, there is MUCH potential for plot complications. And what makes this different from standard superhero series is, the Aspect is not fighting “crime” or “criminals” but also legitimate heads of state when they are inclined to do Bad Things.
I had this idea once that may not be original, so please tell me if it sounds familiar.
During WWII, after a mission goes terribly wrong, an Allied squad is annihilated, leaving just three soldiers alive, with no commander. Shellshocked and demoralised, they go AWOL. They dress as Germans and steal a Panzer tank. Chased and almost caught by both sides, they manage to stay ahead, until they accidentally find themselves inside a German encampment, where they have to fight for their lives.
I have an idea for a rotoscoped biopic called The Gary Coleman Story. It would be epic in nature with concert footage mixed in to the ongoing tale. I mailed myself the screenplay; don’t get any ideas.
I’d like a medium-budget biopic of Edwin Arlington Robinson. One of those poorly-lit period pieces where everyone is terribly uptight and emotionally constrained. Starring Johnny Depp in a role where he’s not being Keith Richards for fucking once.
Seriously, I think that’d be cool.
I think *Family Guy *beat you to it: Passion of the Christ 2: Crucify This. And even that was essentially the same joke as this: Gandhi II.
The Burden Of The Beasts: It becomes possible to alter the vocal chords of pets, farm animals etc. so that they can speak. At first this is used strictly for research but it soon becomes fashionable to have Speech Pets in the home, until we start realizing what they really think of us.
edited to add: The operation does not alter their intelligence in any significant way-No “Planet of the Apes” scenario.
Steel Road
As robots increase in complexity, they gain enough intelligence to act independently. Amiable and friendly, they are nevertheless powerful and can appear intimidating. After an incident starts to make him question some home truths, one robot decides to seek more facts about his origins, and starts walking across the country to find his Maker. On the journey he meets other robots with different purposes who join him on his adventure, each contributing their particular skills to aid the quest.
I’d do a version of Titanic, but I would set it underground with Chilean miners.
Straight Dope: The Motion Picture - A group of hetero-sexual pot smokers embark on an online journey to change the world. Little do they know, they are merely part of a huge conspiracy run by aliens wearing Birkenstocks.
An old-style sand 'n sandals Biblical epic, where the people talk in ordinary, colloquial English - no anachronisms, just showing people back in the day speaking more or less the way we do. “Happy Birthday, Mom!”, instead of “I greet you, my mother, on the day of your birth”.
Stuntmen On Vacation: Originally brainstormed with the “Three Amigos” gang in mind, the movie follows a trio of Hollywood Stunt Men on a cross-country road trip. As you would expect, they run into all kinds of comedic situations where they put their job-related skills to use.
