Query: Funny yesterday, funny today, will still be funny 20 years f

For all the times I've seen The Producers, I never tire of it. And I'm continually haunted by one question: who is funnier? Dick Shawn? Or Kenneth Mars?Shawn, as LSD, the star in the Bialystock/Bloom production of "Springtime for Hitler" is outrageous, broader even than his wonderful turn in `It's a Mad Mad Mad Mad World'. Mars, who many will remember as W.D. `Bud' Prize on "Fernwood Tonight", is spectacular as Nazi pigeon ranger cum playwright, Franz Liebkind.The Producers never misses an opportunity to stack gag upon gag--physical, musical, intellectual-no holds barred. At 88 minutes the film falls flat at about 65, but at that point you're so full of good humor it really doesn't matter anyway.Kudos to Andreas Voutsinas, and Christopher Hewett, both hilarious in smaller roles.If you haven't seen this film, see it today. If you have, see it again, it doesn't lose a thing the second (or third) time around.
