"An idea is like a cold germ: sooner or later someone always catches it" -Stephen King
Mike Vogel
Mike Vogel gets the lead. This former Pan Am pilot will portray the hero of the show Dale "Barbie" Barbara. Dale is an army vet who tries to flee town after an encounter with Junior and his friends. He can't escape in time, and eventually becomes the person everyone looks to.
Dean Norris
This has to be the most exciting cast member yet. This former Breaking Bad star will go from being the good guy against Walter White to being the villain of the show James "Big Jim" Rennie. Big Jim is a power-obsessed politician who owns a car dealership. He quickly becomes the leader by his own accord.
Alex Koch
This newcomer to the acting community will play the infamous Junior Rennie. Junior is a deeply disturbed college student who's in love with the local waitress Angie. He is also the son of car dealer/local politician "Big Jim." His personality gets him into some pretty strange trouble.

Colin Ford
This former Supernatural and We Bought A Zoo star will play Joseph "Scarecrow Joe" McClatchey. Joe is a very smart 13-year-old who is one of the first in town to figure out the cause of the dome rather than establish order. He is also an avid skateboarder.
Britt Robertson

Aisha Hinds
Hinds (who played on the HBO show True Blood) will take on the role of Carolyn Hill. Carolyn is a LA entertainment attorney who is traveling through town with her partner and their daughter when the dome comes down.
Mackenzie Lintz
This casting announcement went under the radar for a while. Lintz (former district 8 girl on The Hunger Games) was added to the the group. She will be playing a girl named Norrie Calvert. Norrie is a young girl who is friends with Joe and a couple other of the young ones in Chester's Mill.
Nicholas Strong
This former Nashville star will play Phil "The Chef" Bushey. Phil is a local radio DJ in Chester's Mill. His nickname is given to him for his reputation as a high end meth maker.
