Katherine Meisle has joined the cast of the New York Theatre Workshop production of the new Paul Rudnick play The Most Fabulous Story Ever Told . Meisle replaces Jenny Bacon, who broke a bone in her foot during a recent performance, causing the show to delay its opening until Dec. 14. The original opening was to have been Dec. 10. Fabulous began previews Nov. 14.

Meisle is a veteran of such Broadway productions as The Rehearsal and London Assurance, both at the Roundabout.

The Most Fabulous Story is Rudnick's retelling of the Judeo Christian creation myth, pondering what it would be like had God started out by making Adam and Steve, rather than Adam and Eve. Adam and Steve (along with Jane and Mabel) take us on a journey from Mesopotamia to a K Mart on Christmas Eve as they struggle for faith and search for God.

Rudnick's comedy made its debut this summer at the Williamstown Theatre Festival. As he did at Williamstown, frequent Rudnick collaborator Christopher Ashley will direct. Rudnick's comedies include Jeffrey, The Naked Eye, Mr. Charles and I Hate Hamlet, as well as scripts for the films In & Out and Addams Family Values.

The NYTW cast features Obie Award winner Joanna Adler (Benita Canova), Bacon, Becky Ann Baker, Peter Bartlett, Juan Hernandez, Lisa Kron (101 Humiliating Stories), Orlando Pabotoy, Amy Sedaris, and Alan Tudyk (Bunny Bunny). The set design for Fabulous is by Michael Brown, costumes are by Susan Hilferty, lighting design is by Donald Holder with sound by Darron L. West. The New York premiere of Paul Rudnick's The Most Fabulous Story Ever Told began previews at New York Theatre Workshop Nov. 13, for a Dec. 14 opening. For tickets ($45) or more information call (212) 460-5475. NYTW will continue its CheapTix program - holding a limited number (usually 10-16) of tickets and put them on sale two hours before each performance for $10 each.
