HOLLYWOOD, Calif., Jan. 7 /PRNewswire/ -- Multiple Award-winning actor Jason Alexander has been cast to play a space alien leader in an upcoming episode of Paramount Network Television's Emmy Award-winning drama, series STAR TREK: VOYAGER. The episode, entitled "Think Tank" films at Paramount Studios from January 7 - 15, and is tentatively scheduled to air this spring on UPN.

Alexander will guest star as 'Kurros,' a charismatic, but unscrupulous leader of an alien "Think Tank," a legendary group of beings that solve problems...for a price. Cornered by a fleet of ruthless bounty hunters, Voyager seeks help from the Think Tank, whose price for solving Voyager's problem is steep -- they want Seven of Nine (Jeri Ryan) to join their group, and they won't take no for an answer.

Alexander is best known for the nine seasons he spent playing 'George Costanza' on "Seinfeld," a role that earned him six Emmy and four Golden Globe nominations, an American Television Award, two American Comedy Awards and a Screen Actors Guild Award. Alexander is also a Tony Award-winner for his role in "Jerome Robbin's Broadway."
