Young Frankenstein (Mel Brooks) is Number 1.

In no particular order:
The Blues Brothers (John Landis)
Animal House (John Landis)
Almost everything by Woody Allen (Hannah is a masterpiece)
A Fish Called Wanda (is it the correct title? it's the film with John Cleese of Monthy Python and Jamie Lee Curtis)
The Pink Panther: the second film - I don't recall the English title - is my favourite. Peter Sellers!!!
And, talking about Peter Sellers, Hollywood Party.
