Ben Affleck and Matt Damon
After winning a screenwriting Oscar together for “Good Will Hunting” in 1998, the two pals have been inseparable, going way back to the third grade. They’re constantly cracking jokes at each other at awards shows (like the time they joked they were the “Dickheads of the Decade“) and their bromance even inspired an off-broadway play, Matt and Ben. Now, that’s a bromance.
