I reckon I've watched the 80's hit movie 'Cocktail' starring Bryan Brown & Tom Cruise (for those not familiar) on Foxtel 4 times in as many weeks. As I flick through the channels it just seemed to be on. This is one movie I can watch many times and still enjoy it.
There are a few movies that sping to mind:

Shawshank Redemption
A Few Good Men
Top Gun.

What's your top 3 you could watch over many times & still enjoy ?
