1. Life of Brian (best comedy film ever)
2. Alien (ground breaking sci fi / horror set the bar for years, rarely bettered)
3. Unforgiven or any of the spaghetti westerns
4. The Cruel Sea (stiff upper lip Britain at its best)
5. House of the Flying Daggers (martial arts at its best, and beautiful to watch)
But ask me tomorrow and it will probably change to include, Aliens, Watchmen, The Dark Knight, The Maltese Falcon,, Young Frankenstein, Farewell my Lovely, Blade Runner, Master and Commander, Pirates of the Caribbean (first one only), Sense and Sensibility (Emma Thompson version), Crouching Tiger Hidden Dragon, My Fair Lady, Shrek 1 2 and 4, Up, the opening ten minutes of Saving Private Ryan and many, many more.
I love the cinema.
Fight for your opinions, but do not believe that they contain the whole truth, or the only truth.
