Emerson College is well represented in Hollywood, with a list of notable alumni that includes the likes of Jay Leno, Norman Lear, Henry Winkler, Mario Cantone, “Friends’’ producer Kevin Bright, and “Will & Grace’’ creator Max Mutchnick. So it only makes sense that the school itself would have a presence in Tinseltown. On March 8, the college will open its Hollywood campus, an $85-million project that will feature a 10-story, 100,000-square-foot building — located on Sunset Boulevard, no less — and will include classrooms, offices, more than 200 dormitory beds, and parking. The new facility, designed by LA-based architecture firm Morphosis Architects, replaces the college’s current digs — rented office space in Burbank. Building began more than two years ago, but was delayed when a recording studio across the street sued over concerns about construction noise disrupting its business. . . . Speaking of Leno, the “Tonight Show’’ host was in Andover the other day taping a segment for “60 Minutes.’’ With cameras in tow, Leno and “60 Minutes’’ correspondent Steve Kroft stopped at McDonald’s, and Leno worked the counter and surprised a few folks at the drive-thru window.
