Taking a break from his baseball duties, Sox chairman Tom Werner talked to Emerson students this week about his successful TV career, which included producing such hit shows as “Bosom Buddies,” “Soap,” “Taxi,” “The Cosby Show,” and “Roseanne.” He sat down with Emerson prof Jonathan Wacks, who knows a thing or two about TV, having directed “21 Jump Street” with Johnny Depp. The crowd included Emerson trustees Larry Rasky, of the PR firm Rasky Baerlein, and developer/movie producer Steve Samuels, whose credits include the George Clooney movie “Michael Clayton.”
