I agree with the OP about Metropolis. Strongly disagree with Pulp Fiction.
My second would be *Casablanca *or Toy Story. One is the perfect mid-20th C. film in the way *Metropolis *is the perfect beginning (with the political concerns it addresses as much as the styles it invents), the other is a century-end vision of what the future of cinema will be. All hail the Machine.
The Right Stuff.
Honorable mentions: Lost In America, A Fish Called Wanda, Annie Hall, The Terminator, The Godfather, GoodFellas, Back To the Future, and The Quiet Duel.
“Citizen Kane’ It was a breakthrough with lighting and camera techniques that changed the industry. It had a great story, great acting .
The original” War of the Worlds". It was the best of a huge genre of movies . Sci Fi movies were the mainstay in the 50s and 60s and have never gone away. It is under rated and under appreciated.
"Manhattan’
"Ran’ overwhelming and enormous movie.
“Roger Rabbit” You can not compare it to other movies. It was unique.
Definitely The Godfather. Have to say Gone With The Wind, although *Trainspotting *remains my favorite movie for the last 15 years, so it deserves an honorable mention.
Although it has a very different plot,* Notorious *has Claude Rains and Ingrid Bergman (Cary Grant instead of Humphrey Bogart) and I prefer it light years over Casablanca, which was good but not my favorite.
