Yeah, #7 is probably the most obscure one up there - I don't really expect anyone to get that one.

#8 is a truly fantastic movie and shows you how movies should be made. You really should watch that one - especially if you already have it. :)

My sister was watching #14 the other day and I'd forgotten just how silly it was - and perhaps a bit 'adult' at times for its intended audience. Still a lot of fun though. :D
