I really love heist movies, gangster movies, prison movies, and so on. What is lemmy's suggestion that I should watch? Beware I have seen alot.

A couple random ones:

Sneakers is the OG hacker film. If you haven’t seen it, it’s an absolute must. It’s a computer-driven heist film from the 90’s and even though the tech aged, the movie holds up beautifully.

Believe it or not, I’m gonna recommend Solo: A Star Wars Story. It is, at its heart, a sci-fi heist flick.

I can think of one, and you've probably seen it. Papillon from 1973 with McQueen and Hoffman in leading roles.

Heat

If you're looking for something a little different in the gangster genre, the anime series Baccano! might be worth a try.

One I liked a lot is Layer Cake with Daniel Craig

Public Enemy Number One (1953)

It's a gangster comedy, so possibly perfect for you, but perhaps not what you are looking for right now.

How about some classic Danish heist movies? Olsen-banden ser rødt is one of the better in the series.

The Wachowskis' Bound, The Kitchen, and Flawless

"Grand Slam" (1967)

"House of Money" - funny nobody mentioned this one. But only the first heist, the first two seasons. The later ones are not up to par.

A bit outside your prefs, but James Bond parodies Our Man Flint (1966) and In Like Flint (1967) with James Coburn

i was always partial to Attica

Oldie but a goodie, Le Trou is a french film about a prison break, holds up great

Bad Boys , not the Will Smith one but the earlier unrelated movie with Sean Penn. Really good action and some really wild fight scenes involving full cans of soda

I found it super interesting watching the original Ladykillers and the Coen Brothers remake back to back.

Original (with Alec Guiness and Peter Sellers):

Remake (with Tom Hanks and J.K. Simmons):

'Snatch' and 'Lock Stock & Two Smoking Barrels' are two of my favourite gangster/heist movies, both by Guy Ritchie. 'Brawl In Cell Block 99' is a surprisingly good and quite violent prison movie starring Vince Vaughn. A far less violent prison movie I quite like is 'The Green Mile". "Gangs of New York" is definitely worth a watch if you've not seen it. There are also of course the classic heists like 'Italian Job' and 'Ocean's [number]'. 'Catch me If You Can' isn't a heist movie per se but it involves a lot of stealing and subterfuge.

I know there are so many more I can't currently think of but hopefully these few suggestions help to occupy your week off, enjoy!

Cool hand Luke?

I liked the den of thieves movies

How about city of God?

Point Break / Hardboiled / Donnie Brasco / French Connection

Inside Man (2006)

Le Cercle Rouge (1970)

Borsalino (1970)

Un Flic (1972)

Bob le Flambeur (1958)

Before the Devil Knows you’re Dead (2007)

Ronin (1998)

Sexy Beast (2000)

Some obvious ones there that are worth a mention in case you’ve missed them.

Edit:

Things to do in Denver when you’re Dead (1995)

Check out No Sudden Move (2021)

Sneakers The Princess Bride

But I feel this post is just fishing for information on how to commit a heist. You wouldn't download a car.

Das Experiment is probably the best prison film I've seen. It's roughly based on a true story about a psychological experiment set in a prison that goes horribly wrong. I think there was an English adaptation as well but I can't speak to it.
