Have you seen these?
I rewatched His Girl Friday and My Man Godfrey yesterday, on a proper theater screen. Pretty spectacular.
Golden Age I:
My Man Godfrey (1936) - directed by Gregory La Cava
His Girl Friday (1940) - directed by Howard Hawks
Cary Grant is even better than he's supposed to be.
Golden Age 2:
Scarecrow (1973) - directed by Jerry Schatzberg
The best Pacino or Hackman movie you've never seen.
California Split (1974) - directed by Robert Altman
My favourite Altman film. Read about it.
