The two-week extension means that Swayze, who was originally due to finish playing the role of Nathan Detroit at the Piccadilly Theatre on Sept. 23, will now be in London when the stage version of his hit movie Dirty Dancing starts previewing on Sept. 29. That show officially opens Oct. 24 at the Aldwych Theatre.

Swayze's co-star, Claire Sweeney, who plays Miss Adelaide, is due to leave the West End production on Sept. 9 before commencing a U.K. tour of the musical on Sept. 18. Sweeney's replacement has yet to be announced.

Swayze made his London stage debut in Guys and Dolls on July 27. He was originally due to join co-stars Adam Cooper (who plays Sky) and Kelly Price (Sarah Brown) on July 10. But the show announced that Swayze needed more time to recover from a chest infection.

Swayze is best known for his movies "Ghost" and "Dirty Dancing." Onstage he played Billy Flynn in Chicago and Danny Zuko in Grease, both on Broadway.

Michael Grandage's acclaimed revival of Frank Loesser's classic musical opened on June 1, 2005, with Ewan McGregor and Jane Krakowski as Sky Masterson and Miss Adelaide. The original Broadway production of Guys and Dolls opened at the 46th Street Theatre in November 1950, running for 1,200 performances before closing Nov. 28, 1953. Among the premiere cast were Robert Alda as Sky Masterson, Isabel Bigley as Sarah Brown, Sam Levene as Nathan Detroit and Vivian Blaine as Miss Adelaide. Blaine re-created her role for the 1955 film, which also starred Marlon Brando as Sky, Jean Simmons as Sarah Brown and Frank Sinatra as Nathan Detroit.
