Boston’s Ben Affleck embraced some good-looking friends at awards ceremonies over the weekend. On Friday, he had his arms around hometowner Matt Damon, who presented him with the Modern Master Award at the 28th Santa Barbara International Film Festival. On Saturday, Affleck held on to Channing Tatum at the 24th annual Producers Guild Awards at the Beverly Hilton Hotel. (Affleck produced “Argo;” Tatum produced “Magic Mike.”)
