As Frank, Burr brings every ounce of the vitriol his standup fans are accustomed to while still managing to sell his humanity. But his performance is bolstered by an enviable supporting cast who bring their full commitment to the material—particularly Justin Long, who is more known for roles in films such as Jeepers Creepers and Kevin Smith's recent head-scratcher Tusk. His portrayal of Kevin is alternately on-the-nose and surprisingly nuanced, as the character is slowly revealed to have depths beyond that of your average pot-smoking teen.
Also noteworthy is Sam Rockwell, best known for his role as that guy you know in that movie—seriously, he was in Moon, Frost/Nixon, and Iron Man 2 to name a few—who channels Matthew McConaughey better than McConaughey himself could for his portrayal of laid-back neighbor Vic. Rounding out the cast are American Idol alumni Haley Reinhart as Bill, veteran voice actor Debi Derryberry—best known as the voice of Jimmy Neutron—as Maureen, and Jurassic Park's Laura Dern as Sue.
Burr said of his cast to Boston magazine, "They all came from like an acting perspective where they had to do a number of takes, and you felt with each take it became more and more not them and just this person. It was insane... I basically have a lot of talent around me propping me up. Don't tell anyone."
