Jurassic Park (any of the original trilogy)
Heat
Shooter (the Mark Wahlberg one from like 2008)

Jurassic Park is one I've always loved, and though the second one's not as great as the first and third, they're still pretty damn good by today's standards (if a bit cheesy at times).
Heat is an absolute classic. Al Pacino's over-the-top delivery of some lines add a touch of humour to it, and it's a good way to kill three hours (yes, it's THAT long).
And Shooter is one of those films that I watched growing up that stuck with me through high school. (Hell, my first fursona was loosely based off Wahlberg's character, to an extent).
Notable mentions are Hot Fuzz (a good comedy, honestly), Point Break (Classic Keanu Reeves, though I wouldn't put it and Heat in the same movie night because it's another heist film), and Redline (A 2009 anime film that starts about racing and turns into seven different genres by the end).
