I really like a lot of movies coz I'm a movie-a-holic, but if I can only pick one, it has to be...
Mission Impossible III
The fantastic cast and crew!
Although the 4th installment was better action wise, but the 3rd one has that sweet love story element to it. I can re watch MI III for a thousand times and never get bored of it! Whenever Astro has the reruns I will always watch it, that's how much I love MI III!!!
That's why it'll always be my favourite movie =)
