The Voices (2014)

Jerry (Ryan Reynolds) is that chipper guy clocking the 9-to-5 at a bathtub factory, with the offbeat charm of anyone who could use a few friends. With help from his court-appointed psychiatrist, he pursues his office crush (Gemma Arterton), but their relationship takes a sudden murderous turn after she stands him up for a date.

Guided by his evil talking cat and benevolent talking dog, Jerry must decide whether to keep striving for normalcy or indulge in the sinister.
