Under the Dome (season 1)

The first season of Under the Dome (TV series) premiered on June 4, 2012 and featured 13 episodes. The season takes place in Chester's Mill, Maine, a small American town that suddenly finds itself totally cut off from the rest of the world when an invisible, impenetrable barrier, referred to as "the Dome", mysteriously appears around it. While a contingent of the town's remaining government tries to maintain order, a small group of outsiders, led by Army veteran Dale "Barbie" Barbara (Trevor Donovan), attempts to uncover the truth behind the Dome and how to escape from it.

Main Cast
Trevor Donovan as Dale "Barbie" Barbara- A former Army lieutenant (initially referred to as a former captain by Colonel Cox), Barbara became a drifter after separating from the Army. Trapped within feet of the edge of the Dome, witnessing a woodchuck cut in half by the event, Dale was attempting to flee the town after a confrontation with Junior Rennie and his friends. Dale soon becomes the U.S. government's choice to run Chester's Mill.

Amanda Righetti as Julia Shumway- A cynical woman who owns and edits The Democrat (despite being a Republican), the town's local newspaper. Julia often feels the need to prove a point and expose those she sees around her. Julia becomes the conduit between Colonel Cox and Dale Barbara via her cell phone. Julia and Dale have a budding romantic relationship. Both Dale and Julia are gutsy and tough, brave enough to try any chance they might have for survival. Julia comes from a family of news executives; the newspaper is a family concern. She was groomed early for success and was viewed by her peers as a "goody-two-shoes". A confrontation with her classmates in fourth grade caused her to rethink her status and changed the course of her academic career; however, this same confrontation is key in helping her formulate a plan to end the siege.

Donal Logue as James "Big Jim" Rennie-power-obsessed second selectman of Chester's Mill based on Dick Cheney, owner of a used car dealership and the biggest crystal meth lab on the east coast. When Chief Perkins is killed on Dome Day, Big Jim becomes the de facto leader of the Mill. He is owed favors by virtually every person of authority in town, and is rubber stamped by Andy Sanders, the grieving and incompetent first selectman, and Pete Randolph, the new, incompetent town police chief. Big Jim directly controls both Andy and Pete through most of the show.

Nick Roux as James "Junior" Rennie- Junior is a small town thug and son of the most influential man in Chester's Mill. After he is deputized, he recruits new police officers for his father. Junior gradually devolves from a thug to a bitter, angry sociopath, suffering from a brain tumor disguising itself as migraines. He particularly hates Dale Barbara, who laid a beating on Junior and his friends even though they outnumbered him. Dale could have had Junior arrested for assault, but Dale was an outsider and Junior's father was Big Jim.

Drew Fuller as Eric "Rusty" Everett- A kind-hearted physician assistant at Cathy Russell Hospital. Rusty is married to Linda Everett, a police officer, and has two young daughters, Janelle and Judy. His children are the first of many to experience seizures and prophetic visions from the device that generates the Dome.

Jimmy Bennett as Joseph "Scarecrow Joe" McClatchey- A 18-year old student and a dedicated skateboarder at Chester's Mill High School. Joe is a dedicated skateboarder along with his two friends, Norrie Calvert and Benny Drake. Mature and intelligent beyond his years, Joe is one of the first in the town to seek answers for the cause of the Dome rather than try to establish a semblance of an order. He organizes a protest at the Dome's wall, assisted by Norrie and Benny, and manages to rally the town before an incident calls the entire protest off. He later becomes a valuable ally of Dale Barbara, assisting him in providing a video feed during the incident early in the show where the government sends a missile to try to destroy the Dome. Afterward, he continues to make an effort to find answers to the Dome with his friends. He may have a connection to the dome that he, and no one else, can quite explain.

Dylan Minnette as Benny Drake- A 18-year old student and a dedicated skateboarder at Chester's Mill High School. Close friend of Joe McClatchey. He helps Joe and Norrie Calvert search for the cause of the dome.

Chris Carmack as Peter Randolph- Pete becomes Chief of Police after Duke Perkins' death. He is fairly simple minded and is easily manipulated by Big Jim, who secretly considers Pete his idiot. It is through Pete that Big Jim is able to expand and control the Mill's police force.

Olivia Wilde as Linda Everett- Another police officer from the original force, she is fired because she is married to Rusty Everett. Her two daughters are Janelle and Judy Everett.

Jessica Stroup as Jackie Wettington- A police officer on the original Chester's Mill force, she is fired once Big Jim brings enough of his own recruits.
