"I've kind of been texting him back and forth, and he's doing great and [wife] Lucy is doing great," Affleck, 36, told PEOPLE on Wednesday at the Democratic National Convention.
Still, Affleck's mind was not far from his old Cambridge pal, who is fast becoming odd man out in his Miami home, what with the addition of little Gia to his strictly female brood of wife Luciana and their daughters Isabella, 2, and Alexia, 10.
Not that Damon – PEOPLE's Sexiest Man Alive – has any problem with that.
"Anybody who has a child is excited, I think, no matter what the gender is. They are thrilled," says Affleck. "The thing that people really want, when you get down to it, is a healthy child."
As for his involvement in History, Brolin admitted that he first discovered the book through a speech in which it’s referenced in Good Will Hunting, which Moore produced. “I had a very strange obsession with Matt Damon,” Brolin joked.
Quantum of Solace star Daniel Craig has stressed that the new James Bond film bears little relation to the Bourne trilogy.
Matt Damon's role as the amnesiac secret agent revolutionised the action genre and was held to be a refreshing change to the style of the Bond franchise.
And with Bourne trilogy stunt director Dan Bradley working on the 22nd Bond movie as second unit director, comparisons between the series of films are likely to continue.
Craig added: "Sorry to be political about it but I'm certainly not going to get into a p*****g competition with the Bourne fans."
One such intimidating moment was preparing to play a Wall Street Journal reporter in the upcoming political thriller "Green Zone," costarring Matt Damon. "Talking about weapons of mass destruction was really over my head," she admits. "There were some days on set when I didn’t know what the hell I was talking about, but I just dove in."
