The show is becoming a forum for many a Broadway return. Over the weekend, Zoe Caldwell, who has won four Tony Awards over her career, the most recent being for Master Class, guest starred. Her stage appearances have been infrequent over the past two decades and, in fact, her involvement in The Play What I Wrote marks her first Broadway appearance since Master Class in the mid-90s.

Liam Neeson was the second secret celebrity guest star in The Play What I Wrote. The film actor appeared at the Tuesday, March 11, and Wednesday, March 12 performances. Neeson followed Roger Moore, filmdom's James Bond, who was the mystery guest during the show's first weekend of performances.

The Play What I Wrote, a quirky London theatrical sensation, began its American premiere at Broadway's Lyceum Theatre March 7.

Kenneth Branagh directs the work of Hamish McColl, Sean Foley and Eddie Braben, featuring actors McColl and Foley and Toby Jones on stage. The 2002 Olivier Award-winning play "revolves around Hamish, who no longer wants to be part of his comedy double act with Sean," according to production notes. "Instead, he wants to see the play he has written, A Tight Squeeze for the Scarlet Pimple, properly mounted on the Broadway stage. But before this can happen, he needs a major star to play the supporting role to his lead role."

Moore starred in several movies as Agent 007, including "Live and Let Die," "The Spy That Loved Me" and "Moonraker." He was also star of the television series "The Saint." The original London mounting was an homage to the famed-in-Britain-but mostly-unknown-in-the-U.S. comedy team of Ernie Wise and Eric Morecambe.

The Lyceum is at 149 W. 45th Street. For ticket information, all (212) 239-6200.
