A special "Star Wars"-themed edition of the hit U.S. television game show "Deal or No Deal" is set to air later this month, NBC announced.

The two-hour "winner take all" episode is to run April 28 and feature appearances by Chewbacca, R2D2 and Carrie Fisher, the actress who played Princess Leia in three films in the "Star Wars" franchise.

The character of Darth Vader is also expected to fill in as the "Deal" banker, while the show's models are to be replaced by Imperial storm troopers, the network said.

In the episode, two contestants will compete for nearly $2 million. The players will each play their own game and whoever has the highest amount at the end of his or her game will take home both winnings, leaving the other with nothing, NBC said.
