Morgan Freeman and Tim Robbins in The Shawshank Redemption (1994)
Andy (Tim Robbins) and 'Red' (Morgan Freeman) in The Shawshank Redemption
This comes from the legendary Mark Twain and I think his vision of friendship comes the closest to one everyone would fully agree with... and that most movies seem to have proved right or relevant.
It would be impossible to list all the movies that deal with friendship but there are enough in IMDb Top 250 to cover a wide range of selection of memorable friendships (excluding mentoring, father-and-son or any relationship based on protection or a specific learning and/or teaching)
So, which of these enduring (and endearing) friendships from a Top 250 movie (or series) best defines your personal idea of 'friendship'?
(and does it really have to be from your favorite movie?)
