There’s never been a Boston crime movie quite like “Conned.” A comedy shot in and around Boston, it’s about gangsters who happen to be deaf.

“Conned,” which screens at Sunday afternoon at the Somerville Theatre and will be available on DVD and video on demand Tuesday, was written and directed by Arthur Luhn, a Boston University graduate who lives in Randolph. Luhn, who was born deaf, wanted to make a film in which deaf characters figure prominently in a story that has nothing to do with their deafness. “I find most crime movies dreary and depressing. I wanted to do something completely different,” says Luhn, signing through an interpreter. “It’s empowering because there’s no reason for the characters to be deaf in the film. They just are.”
