I think it is just about the perfect comedy film ever ( not bad for a 76 year old production! ) It enthralled me when I was young and is still as capitavting now; it amazingly just doesn't seem to date and even though I seem to know all the dialogue off by heart the laughs are still as fresh. It really has everything, including great actors, great music and so many funny one liners and scenes. The state room scene, the Sanity Clause, and all scenes with Groucho teasing Sig Ruman, and the imperious and marvellous Margaret Dummont! If you had to watch just one film to understand the Mark Brothers genius then this is it!!
