Today in Hollywood: Run DMC reunite

Run DMC performed for the first time in more than a decade on Sunday at the Made in America festival in Philadelphia. Joseph "Run" Simmons and Darryl "DMC" McDaniels performed hits including It's Tricky, My Adidas and Walk This Way. In a poignant moment, Run talked about the group's break-up following the death of member Jason "Jam Master Jay" Mizell in 2002. "After his assassination … we put a silence on the group," he said. Jay's sons, nicknamed TJ and Jam Master J'Son, also performed a number with the duo. - AP

Hawke confirms third Before Sunrise

Ethan Hawke has announced to MTV News that he and the director Richard Linklater are in Greece writing a third part to their 1995 romantic drama Before Sunrise. "If it works out, we'll film it, and if it doesn't, we won't," said Hawke. "It's super good. We're here workshopping it, trying to create a great script." The film's other star, Julie Delpy, told New York magazine last month that she is co-writing the script with Linklater and Hawke.

Gosling to direct Hendricks in debut

Ryan Gosling is set to make his directorial debut in How to Catch a Monster, headlined by his Drive co-star Christina Hendricks and produced by Marc Platt and Adam Siegel. "I am very appreciative to Marc and Adam for being so supportive and I look forward to making this film with all of them," said Gosling in a statement. The fantasy noir, described as "set in a vanishing city in a dark underworld", was written by Gosling. Production is slated to begin mid-2013.

Usher puts personal troubles behind him

Usher has had a turbulent few months, but now he's back on stage. The R&B singer kicked off this week's iTunes Festival in London. Over the summer, Usher coped with the death of his stepson and a custody battle over his two sons, which he won. Usher joked in a press conference: "Man, it's like, 'Shut up and entertain, we don't care about your personal stuff'." The iTunes event, running until September 30, features over 60 artists including One Direction, Lana Del Rey and Alicia Keys. - AP
