La Cage Aux Folles is a hilarious French farce that spawned two sequels, a Broadway musical, and an equally good, but almost scene for scene remake (The Birdcage). Some people have said the film has stereotyped gay characters and that Serrault's constant screaming is annoying. I disagree--I found nothing offensive about the characters (gay men like Serrault exist, we've all met them!) and his screaming is actually very funny and brilliantly duplicated by Nathan Lane in the remake.
This is a great film, funny, touching, and simply wonderful. It was nominated for 3 Academy Awards and won the Golden Globe for best Foriegn Film. How many gay-themed films can you say that about?
P.S. Please ignore the R rating--the subject matter, which was pretty risky for 1978, has gotten rather tame. By today's standards, the film would easily get a PG-13.
