I would like to add some movies that i think i can watch anytime...and even find myself watching again and again......
1.October Sky
Beautiful story of a boy trying to build a rocket, and in the process understanding what is important in life.This is one epic story of relationships, hardwork, friendship and passion

2.V for Vendetta - I am surprised no one has mentioned it yet.This movie can truly be called a masterpiece, where each dialogue signifies so much, that each time you see it, you understand the depth of the story more and more.

3.Hera Pheri- Again, a briliant and original comedy, which went to become a classic.

4. We are Marshalls- This is one sports story that reaches out to you. This is based on a True events that happened at Marshall university, in which the whole football team died in plane crash.After the event, the staff and a new coach set out to build a new team.
There is one particular scene in which the director of university says about how bad the town is hurting and how they just wanna play football.....well that dialogue there instantly takes your heart away.....and adds this film to your favorites...

5. Little Manhattan- This is the sweetest love story ever told about a kid, exploring different aspects of love, falling in love and getting the depth of it.
P.s- its very funny too :)
