LATEST: Former Ally Mcbeal star Jane Krakowski has been forced to pull out of contention for the Broadway revival of movie musical XANADU because of commitments to her TV show 30 ROCK. The actress was the favourite to play roller-skating muse KIRA in production - a stage adaptation of Olivia Newton-John's 1980 movie - but she has been forced to gracefully step down. According to website, Krakowski participated in recent workshops for the production, which will star stage veteran Ben Vereen in the role Gene Kelly played on the big screen. But the project, which is set to open later this year (07), conflicts with her role in hit US sitcom 30 Rock.
