Actor Mark Ruffalo was at the Globe on Monday to do research for his new movie “Spotlight,” in which he’ll play Globe investigative reporter Michael Rezendes, a member of the Pulitzer-winning team that broke the Catholic sex abuse scandal. Ruffalo was seen in the newsroom, the cafeteria, and the library — not that we were following him. Ruffalo’s costar Rachel McAdams has been spotted around Boston, so she must be researching for her own role in the film (she’ll play former Globe reporter Sacha Pfeiffer, who’s now a star at WBUR). . . . Seth MacFarlane, who’s in town to film “Ted 2,” surprised the performers at the midnight show, “Raunch,” at Improv Asylum over the weekend. Joining him for a photo were Alex Greenwald, Vicki Hanes, Ed Lees, Kelly Dooley, Christine Cuddy, Tim Johnson, Brian DiBello, Ryan MacFarland, and Mark O’Connell.
