Main cast
Keith Carradine as Nick Savage – the irritable patriarch of the Savage family. His wife left him ten years prior to the pilot episode. He is quick-tempered. Although some of his parenting style is regarded by his sons as unfair, he always shows that he has his sons' best interests at heart and is very concerned for their education and well being. However, his solution to most problems is to get angry, a solution which seems to have been picked up by his sons Chris and Kyle and occasionally Jack. He works as a firefighter along with his younger brother, Jimmy. Although uptight and ill-tempered he is shown to be a "cool" dad allowing some things slide with his sons for their happiness usually with girls.
Shaun Sipos as Jack Savage – the eldest son. He is considered the "cool" brother and has many girlfriends. He is an aspiring musician who sings and plays the guitar. Jack often takes on the role of leader for the boys and always organizes, stages, and tries to hold the brother together, mainly against their father. Jack is often envied tremendously by Sam mainly due to the reason that Jack is more popular in school and has many girlfriends while Sam is nerdy and finds it hard to get girls. Although Jack tries to seem independent, he often shows a lot of caring for his brothers, especially T.J.
Erik von Detten as Chris Savage – A varsity letterman who is considered a dumb jock, as he was failing five different school subjects. Chris seems to have a very strong conscience as opposed to Kyle. Chris often agrees with Jack due to Jack's great persuasion skills, combined with the fact that Chris is easily swayed and not that bright in the head. He also shows violence as a way of solving his problems as he's not good with words. He clearly shows his superiority over his younger brothers through his often used punishment "You're going in the pit" inherited from his father.
Andrew Eiden as Sam Savage – the middle son considered "black sheep" of the group, as he is responsible and does his school work. He is an honor student who enjoys studying and being with his girlfriend. He is known for getting A's in school with the exception of P.E. Sam was always considered by the boys' father as the easiest one to break when the boys were staging a front.
Evan Ellingson as Kyle Savage – A rebellious teenager who is unruly and constantly causing chaos. He has little regard for the safety of himself or others. Unlike his brother Chris, Kyle shows a lack of a conscience. He rarely feels bad or guilty about anything he does. He frequently hangs around with his younger brother T.J., whom he often convinces to do stupid things. Despite his misbehavior, he appears to be more mischievous rather than malicious. He is reckless and proud.
Jason Dolley as T.J. Savage – the youngest son who basically does everything Kyle tells him to do. He constantly shows his obsession of farts. T.J. is a typical little brother. He is considered cute but deceiving with a reckless side.
