A lot of my picks have already been mentioned. I’ll add Sky High. A friend dragged me and our group to it. I was reluctant - a Disney Channel Original, but paying theater prices to see it? But, it was just fun. I honestly think it may be the best live action version of the school-for-super-heroes trope. It’s also, for my money (literally), one of the top 10 super hero movies overall.
I’ve seen Trainspotting more times than I’d care to admit. I think it is tied with Pulp Fiction for having the most impact on me.
Ninotchka, for comedy.
Raiders of the Lost Ark, for mindless action.
Zulu, for more serious action.
Casablanca, for witty banter.
I get a huge kick out of Bridget Fonda’s character Melanie. Louisssss chicken shit 
But I never read the book, just downloaded The Switch from Hoopla it’s the 1st book in the Ordell Robbie and Louis Gara series. I’m looking forward to it!
Yes!! Definitely read Rum Punch. I read it fifteenish years ago on my first trip to St Martin. I read it on the beach at Friar’s Bay.
Since then it’s been my first beach read ever year until COVID-19 busted the yearly thing. I read it instead on the couch at home, though.
I saw “Hellzapoppin” (Olsen and Johnson) on TV when I was a kid 60 years ago. My mother saw it on Broadway. But I’m not sure I ever saw it from start to finish. A few years ago my wife gave me a VHS version (kind of pirated, it is not officially out) for Christmas. I banned everyone from the living room when I started to watch it because i couldn’t imagine it being as good as I remembered.
It was better. I invited people in for the amazing first scene, where a cab delivers O & J to hell. (Finally a cabbie who went where I told him to go.) They all stayed to watch the whole thing.
Close runner up is 2001, a movie I had read all about, and sweeter because I saw it for the first time in Cinerama on a school trip I had instigated.
The first time I saw A Clockwork Orange, I caught it somewhere in the middle.* I was instantly hooked and watched until the end although I didn’t really know what was going on. I loved it even more the next time, when I started at the beginning.
.* And I caught it at a rather tame scene, when Alex is talking (in a relatively normal manner) to the chaplain in the prison.
I always thought that movie was underrated. I enjoyed it lots. I could never understand the snobbery toward it.
One of my favorite films.
I’ve see it many times - and I am always amazed at the acting, score, and cinematography.
But that had an upbeat ending. For a truly depressing ending remember “Old Yeller”
I was roughly 5 so literally all I remember is sobbing so hard I tried to run out of the theater.
In retrospect maybe not the best thing to take a group of kids to! Old Yeller is a movie I never saw - which, yeah. Happy I didn’t.
The Right Stuff. When the credits rolled, I thought to myself “Wait, I thought this was supposed to be a three hour movie?” Then I looked at my watch and sure enough, it was three and a half hours later. That movie had my complete and total attention. I had no idea how much time had passed.
Another vote here for The Princess Bride. A friend took me to see it at some little art house theater where you had to sit on the steps. I didn’t have high expectations for the movie but after it was over I immediately wanted to see it again.
Also Miracle. I’m a huge hockey fan and I knew how the movie was going to end but damn if I wasn’t torn between cheering and crying at the end.
“Indeed!”
For flat-out joy, it has to be Raiders of the Lost Ark. I was 13 or so when it came out, and that movie was just MADE for 13-year-old boys. Wonderful series of adventure scenes. Nazis! Tomb idols! Chases! Egyptian secret chambers! Supernatural revenge!
A close second for Airplane! About the same age. I had never seen anything like that. At one point I was laughing so hard I fell out of my theater seat and couldn’t breathe. My dad was seriously worried for a few moments.
(Phoebe Buffay) What kind of a sick doggy snuff film is this!!!
A real oldie, ‘Dinner At Eight’ (1933) - rather dated, but most of the themes - social climbing, sex addiction, suicide, faded celebrity and downward spiraling celebrity - never get old. John Barrymore is amazing, as is Jean Harlow, and the dialogue is often side-splittingly hilarious. (“I know men, my dear…I should, it’s been my life’s work.”)
not the most entertaining movie but i remember laughing my ass off and rolling my eyes at the same time seeing revenge of the nerds of course i was 12 and seen animal house a dozen times … same with porkys … …these days that movie is all kinds of wrong … and I still say the greatest car chase I’ve ever seen is the entire blues brothers movie …
lol, I saw pulp fiction 6 times 2 alone and the other 4 with friends and family for the shock value …
heh, I watched it on an airplane when I was 10 years old, the guy sitting next to us who didn’t say 10 words to me and my brother the whole flight paid 9.50 apiece for the earphones for the both of us … said we needed to do something fun …
He needed to do something to keep you from bugging him the whole flight. 
It’s my favorite superhero movie too! And entertaining AF!
