These are the first five non-Star Wars films to pop into my head when confronted with the question, and I don’t feel like agonizing over it so I’ll leave it at this for now. Presented in release order because I don’t believe in ranking the top tier.
Lawrence of Arabia (1962)
Dr. Strangelove, or: How I Learned to Stop Worrying and Love the Bomb (1964)
Jurassic Park (1993)
Rushmore (1998)
There Will Be Blood (2007)
