Make small changes and vastly improve a movie!

Avatar:

Have some Navi on base using human avatars, make them part of the efforts of the corporation to have relations and negotiations and they have come to enjoy the human’s lifestyle. It would help make the film more complex and thought provoking.

Go into greater detail about Earth and why the unobtanium is needed, make it a desperate bid to save billions.

Most importantly Sully should realize that if he wins and the humans are kicked off Pandora he is a dead man once the limited air tanks run out, he should choose to fight anyway because he believes it right and die. It makes his decision have weight, he can choose to fight for what he believes in but it will cost him dearly.

Paranormal Activity:

Early in the movie the girl refuses to be filmed during sex.

So instead of her just standing there and watching her husband all creepy like for hours at a time, she should have been a sexual aggressor. I think that would have been much creepier than have her just stand and stare.

League of Extraordinary Gentlemen: I guess “adapt the damn comic” is too big a change, so…

–Get rid of Mina Harkness’s vampire powers and make her the leader of the group. She has a much more interesting ability anyway: She’s unafraid to challenge bigger, more powerful men.

–Lose Tom Sawyer, or at least make him the right age.

–Lose Dorian Gray.

–Have Nemo turn out to be Holmes in disguise. They dropped hints in the comic that he might be…

Godfather, Part 3: Delay production and make Winona Ryder Corleone’s daughter. Get rid of the dialogue nods to previous movies.

Retrofit each projector with a reservoir of trichloroethylene and a squeegee upstream from the lens.

I came in to say don’t spoiler what is actually going on in Dark City in the first 30 seconds, but on checking the IMDB it seems they have already fixed that.

Star Wars Episode 1: Kill off Jar-Jar Binks 1 minute after he appears.

Titanic - Have old Rose graciously thank the salvage crew for the nice helicopter ride and a chance to relive her memories. As a thanks, she slips them the Heart of the Ocean necklace instead of tossing it overboard like the little bitch she always was.

Four Weddings and a Funeral–replace Andie MacDowell with just about anybody. Could tweak the actual character, too.

Or maybe just remove her all together…

Still a great movie, though.

I’m so glad someone else thought of this. It’s what I would have wanted to see. Why waste such a valuble item? At the very least she could have sold it and donated the money to start a charitable fund, perhaps for arts scholarships, and named it for Jack.

I just couldn’t like Rose. She was always running away. She never even told her mother she survived. If she wanted to break away she could have waited, got on her feet as she so obviously did, and then contacted her mom. Sure, mom was bitchy too, but in spite of everything I think she loved Rose.

Cloverfield: Have the movie not be about a damn love story. Just pieced together footage from multiple cameras after the fact

Matrix: Come up with some other reason to explain the set-up other than using comatose humans as a power source. (Or whatever the precise BS was.)

The Lord of the Rings films:
No dwarf tossing. No elven shield surfing. Have Faramir be a wise man. (And a bunch more.)

Supposedly the original script says that the machines are using the humans as a kind of neural net/biological computer, they need the matrix to keep the human’s minds chugging along. Studio peeps thought this was too confusing for the audience and requested the change. I’ve seen this repeated several places.

i was coming in to say the same thing as PeskiPiski. Yes, get rid of Andie McDowell in “Four Weddings and a Funeral.”

Put a counter in the corner of the screen in Groundhog Day, so we know how many times he’s actually repeated the day.

This applies to almost all movies: make nudity the norm for all the attractive women – wherever they are, whatever they’re doing.

And Groundhog Day. And everything else.

Return Of The Jedi:

Replace the mission to take out the second Death Star with a daring raid on Coruscant for <insert reason>, things play out much as they did from here with the infiltration for our heroes to turn off a planetary defense and Luke and Vader confronting Palpatine and a rebel fleet is waiting for the signal to attack.

Instead of feeling like a retread of the first film with improved FX this would be epic and give us a glimpse at Coruscant. It would make the rebels victory more believable as well if they controlled a vital piece of real estate like Coruscant(maybe they only succeed because Palpatine in his arrogance to turn Luke left some defenses down).

I second a quick death for Jar Jar Binks. War over trade federation rights is hell.

2010 – very simple – just remove every one of Roy Scheider’s voice-overs. It won’t be all you can do, but it immeasurably improves the result. Look at what it did for Bladerunner.
The Day the Earth Stood Still – the Keanu Reeves version, of course. This one needs a lot of work, but just fixing the CGI of Gort so that he doesn’t look like a bloody cartoon will i mprove things. The rest of the film’s CGI looks state-of-=the-art, so why skimp on the robot. Also change the stupid ending.

Pink Flamingos: The dog is constipated.
