Matt Damon will celebrate his 45th birthday on 8 October, 2015 (Thursday). And with his recent release "The Martian" breaking all records and garnering rave reviews, it looks like the actor has good reasons to have a big bash this year.

On the occasion of his birthday, let's take a walk down memory lane and bring back the times he has shared with his best pal Ben Affleck. We have heard various stories about marriages and relationships in Hollywood, but the story of Matt Damon-Ben Affleck bromance is just too adorable.

Life is incomplete without a true friend and the two actors have proved this by standing by each other through thick and thin of times. On his birthday, we list out some interesting facts about Matt Damon and the "Batman v Superman: Dawn of Justice" actor's friendship:

  • Damon and Affleck are close friends since childhood and grew up in houses just two blocks away from each other. The Bostonians are, in fact tenth cousins.
  • Matt and Ben used to play "Dungeons & Dragons", video baseball, and short-stop in Little League. They enjoyed watching Godzilla and Kung Fu double features on Saturdays and followed the adventures of "The Super Friends" and "The X-Men" when they were kids.
  • Matt first began acting at the age of 10 while attending Rindge & Latin prep school alongside with Ben Affleck.
  • Before Damon and Affleck made it big in the industry and became popular, the two of them were so broke that they shared a joint bank account.
