what a question!!
Fascinating to see such a wide range of responses.
I guess it would be a bit boring if we all liked the same films..
For what it's worth, I think mine would probably be "Back to the Future". Loved that film when I was a kid.
Spaceballs? One of my favourite Mel Brooks movies.
I'd also like to mention "Gremlins" (don't think I saw it in the thread) and "Planes, Trains and Automobiles" - Steve Martin and John Candy made a funny comedy act in this film.
