[During the 20 year Ghostbusters reunion commentary on the Ghostbusters DVD] "Acting is all about big hair and funny props... All the great actors knew it. Olivier knew it, Brando knew it." "At first I would get mail saying, 'Oh, you must be a Christian because the movie [Groundhog Day (1993)] so beautifully expresses Christian belief.' Then rabbis started calling from all over, saying they were preaching the film as their next sermon. And the Buddhists! Well, I knew they loved it because my mother-in-law has lived in a Buddhist meditation centre for 30 years and my wife lived there for five years." - remarks to the New York Times on the ecumenical popularity of Groundhog Day (1993). [On whether he and Bill Murray would consider doing a third Ghostbusters movie] "My attitude is generally like Bill's old attitude-- there's no point unless it has some interesting quality or something to say about the subject. Personally, I don't rule it out. I'm skeptical, but maybe it'll work." " Everything we see has some hidden message. A lot of awful messages are coming in under the radar - subliminal consumer messages, all kinds of politically incorrect messages..." "Chicago still remains a Mecca of the Midwest - people from both coasts are kind of amazed how good life is in Chicago, and what a good culture we've got. You can have a pretty wonderful artistic life and never leave Chicago." "I'm at my best when I'm working with really talented people, and I'm there to gently suggest or guide or inspire or contribute whatever I can to their effort. It's not like I'm gonna tell Robert DeNiro how to act - but I could provide him with useful anecdotal material from my own life or other people I've known, or actual psychological information, or insights into his character. The technique's up to him. But there are ways to gently urge an actor to pick up the pace or slow it down or focus more, to go bigger or smaller. Some actors are very open right at the beginning - they say, "You only need four words with me: `Bigger, smaller, faster, slower.'" "Well, I never made big films to make big films; the scale's been appropriate to the content." "Well, for me, it's the relationship between comedy and life - that's the edge I live on, and maybe it's my protection against looking at the tragedy of it all. It's seeing life in balance. Comedy and tragedy co-exist. You can't have one without the other. I'm of the school that anything can be funny, if seen from a comedic point of view."
