Top 10 movie of all time

What could be the top 10 movies of all time in the world. I always like to ask this question to friends who are having a good taste of movies. What are the qualities which make them great, unforgettable and entertaining.

Why these great movies are loved by people of every country ? Is there any relationship between the great movie and the revenue generated by that movie for their producer ? Why commerce comes in front of creativity ? Is there any possibility of making fine balance between creativity and the commerce ?

As far as my knowledge goes there is a great possibility of making a fine balance between creativity and the the commerce. Godfather and Shawshak Redemption are the example of movies with a high level of creativity with commercial success. But there are example of movies which have scored very badly at box-office but have established the new benchmarks of creativity. Citizen Kane is the example of movie falling under this category.

Here is the list of movies which every movie lover must watch before he/she die:

(1) Life is Beautiful
(2) The Godfather
(3) The Shawshank Redemption
(4) Casablanca
(5) The Lord of rings-1
(6) The Matrix
(7) The Silence of Lambs
(8) Taxi Driver
(9) One flew over the cuckoo's nest
(10) Forrest Gump

There are many more movies which I want to share with readers. Those movies will be discussed in subsequent posts in this forum.
