Perhaps best known as Ian Gallagher on the Showtime comedy-drama series “Shameless,” Cameron Monaghan is a bright, shining star who’s currently headlining the drama-thriller “Shattered” with Frank Grillo, Lilly Krug, and John Malkovich. I sat down with Monaghan to talk about the film.

“Shattered” is now out in select theaters and video-on-demand.
