Boston actor Mike O’Malley was at the Television Critics Association press tour in Hollywood over the weekend to promote his new NBC comedy, “Welcome to the Family.” He was asked about late actor Cory Monteith, with whom he worked on “Glee.” O’Malley (inset) said of Monteith (who died July 13 of mixed drug toxicity involving heroin and alcohol), “Ever since I met him — he was the fictional quarterback on that show and the very real quarterback on that set. He was an incredibly warm guy, a guy who was welcoming to everyone who came on that show from the beginning through the new folks who came on this past year. . . . I loved working with him. He was a great guy. I miss him very much.” . . . Also at the TCA event were execs from ReelzChannel who promoted their fall documentary, “JFK: The Smoking Gun.” They claim the special will reveal the identity of a second shooter in the John F. Kennedy assassination. The network aired the movie “The Kennedys” in 2011.
