The new movie "The Voices" is a comedy starring Ryan Reynolds and a talking dog and cat. But it's not the film you think it is. 

Reynolds plays Jerry Hickfang, a mentally unhinged young man who fatally stabs one of his colleagues. The talking cat? He's a voice in Jerry's head... with a Scottish accent.

"The Voices" was directed by Marjane Satrapi, whose other films include "Persepolis" and "Chicken with Plums."

While Satrapi usually only works on films she's written, she says after she read the script for "The Voices," she knew had to direct it. And she knew right away that Ryan Reynolds would make the perfect "likable serial killer."
