The story of the rescue of US diplomats from Tehran after the 1979 Islamic Revolution, has put Affleck back in the spotlight after a grueling period 10 years ago when he became tabloid fodder while dating Jennifer Lopez, and the couple starred in 2003 romantic comedy flop "Gigli".

Damon, with whom Affleck shared a screenplay Oscar for the 1997 film "Good Will Hunting," talked with Reuters about his friend's success.

Q: You must be so proud of Affleck.

A: "I'm just thrilled for him. I'm really happy. I'm not at all surprised, because I've known him for so long and I know how talented he is."

Q: Ben went through a rough patch in the early 2000s when the media was merciless with him, his career and his personal life. Was it rough to watch from the sidelines?

A: "It was tough to watch him get kicked in the teeth for all those years because the perception of him was so not who he actually was. I always felt a knee-jerk need to defend him. It was just upsetting. It was upsetting for a lot of his friends because he's the smartest, funnest, nicest, kindest, incredibly talented guy. And the perception of him was the opposite. So that was tough."
