Three actors have landed recurring roles: Ever Carradine has been cast in Sci Fi Channel's Eureka; Mark L. Young has married into HBO's polygamy drama Big Love; Valerie Cruz has made the cut for Showtime's Dexter.

According to The Hollywood Reporter, Carradine will play Lexi, the free-spirited sister of Sheriff Carter (Colin Ferguson), on the UMS-produced Eureka. She will appear in at least four of eight episodes of the upcoming summer season, which debuts July 29.

On Big Love, Young will play a troubled kid who gets thrown out of the Juniper Creek compound for kissing a girl earmarked for an elder.

In Dexter, Cruz will play the wife of Assistant District Attorney Miguel Prado (the recently cast Jimmy Smits).
