One of my favorite directors
Too bad he wasn't more prolific, but he directed:
The Swimmer (Burt Lancaster's personal favorite)-- 1966-68. I'm rewatching it now.
David and Lisa (Keir Dullea) 1962
Last Summer (Richard Thomas) 1969
to name a few. Definitely of the 1960s, but towers of most directors now.
By the way, you know what my vote for most overrated director is: Soderbergh. Change my mind!
