Some actors read reviews and some don’t. Mike O’Malley clearly does. In Globe critic Ty Burr’s review of “Sully,” he wrote that O’Malley, who plays an NTSB investigator, has a “doorstop of a face.” The actor immediately took to Facebook and offered a $25 gift card to anyone who could post an image of a doorstop that looks like him. There were several funny submissions, but O’Malley’s sister, Kerry, actually had a doorstop custom made with a picture of her brother on it. We know because O’Malley, who grew up in Nashua, N.H. and lives in LA now, posted a picture of the doorstop on Facebook, which prompted one commenter to write: “This holiday season the O’Malley Face Doorstop is the must-have gift.”
