i don't know if they are top 5 but these are the ones that came to my mind now:
1. Matrix (the original)
2. Gladiator
3. Naked Gun
4. There is something about Mary
5. Terminator II
mmm Ok in no order cos that is just too hard!!! look whos talking ( come on this film is great! )
labyrinth ( david bowie at his best mmmmmm )
ghostbusters ( its classic )
the omen
any of the hannibal films
and a thousand more but its so hard to choose what would be your top 5.
maybe we should do the worse films and save eachother time on watching them.
I really wanted to put the davinci code there but the film was a far cry from the book.
ok dirty dancing is up there but if i put the 5 cheesy films i love down ppl would think i was 10 years old, hehehe would lion king count as a film? and i think pretty woman, coctail would be hight up there too lol
