Highlights of his directing career are The Sound of Music, West Side Story, The Day the Earth Stood Still, The Haunting, and Star Trek: The Motion Picture. Oh--and he edited Citizen Kane.
I was a screening of one of his movies while I was in college and he was present. He came across as a very kind man with a real love of films. Some of them are among my favorites...
BTW, the first movie he ever directed was the one he was present for at the screening...
Interesting how his best films (outside of the Sound of Music and Star Trek: The Movie) have gone down as B movie classics. Hell, The Day the Earth Stood Still stands today as one the best, if not the defenitive classic Sc-Fi films of the fifties. It was also one of the first films to depict visitors from another world as friendly.
Holy Shit! Just yesterday I was thinking about when he was going to die too. Train of thought that led me to think of him was directors who had changed their movies after release and then I remembered that he was extremely old.
