I'm not sure he's looking for comedy, but if he was, The Life of Brian would be a more logical choice than Holy Grail.
THat movie is a masterpiece. It makes me cry to realize that they just don't make em like that anymore. Instead we end up with garbage like "Epic Movie" and "Superbad".
I liked Superbad, but I agree with your overall point. Good comedy (in film) is tough to find. Really, TV has been better to comedy than film has.
