According to Spoiler TV:
Michael Raymond-James' character of Dave is a charming and friendly guy from a city in the Northeast who has spent a significant amount of time in low-rent bars. He’s able to disarm with a smile but can quickly turn dangerous. He is the seemingly nice guy who is ruthless and cunning. Fans should recognize Raymond-James from "Terriers" and/or "True Blood".
Aaron Munoz's Tony is quick tempered and does not present himself as intelligent as Dave. He likes women, food, and guns.
