The actor will return to Broadway after 25 years' absence to trade places with the man who created his immortal 'Seinfeld' character, George Costanza.

It doesn't get much more meta-theatrical than this.

Jason Alexander, who remains forever associated with his Seinfeld role of George Costanza — a character modeled by series co-creator Larry David on himself — is back in the alter-ego business.

This time, Alexander will return to Broadway after a 25-year absence to take over for David in his hit comedy Fish in the Dark, in the lead role of Norman Drexel, another part that blurs the lines between creator and character.

The play's limited-run engagement at the Cort Theatre, where it has broken house records, was scheduled to close on June 7. However, due to sell-out business and ongoing ticket demand, the production has been extended through July 19, with Alexander stepping in starting June 9.

"Not only was I fortunate enough to write for Jason Alexander on Seinfeld, but I also had a ringside seat watching his brilliant, indelible performances," said David. "Needless to say, I was thrilled when I heard he was replacing me in Fish in the Dark. Finally I can enjoy the show."

Added Alexander: "I left Broadway 25 years ago because Larry David co-created the show that would change my life and career. It is totally amazing that he also created the show that would bring me back to Broadway. I am thrilled I get to do this hilarious play for him and with this wonderful cast. It is quite simply more fun than any bald man should have."

The comedy about a death in the family opened on March 5 and has been playing to capacity houses and box office north of $1 million a week since previews, grossing $7.8 million to date.

Directed by Anna D. Shapiro, the play's 18-member cast also features Rita Wilson, Rosie Perez, Ben Shenkman, Lewis J. Stadlen and Jayne Houdyshell, all of whom are expected to stay through the extension. Scott Rudin is lead producer.

Alexander won a Tony Award for best actor in a musical in 1989 for his performance in Jerome Robbins' Broadway. His other past Broadway roles have included the Stephen Sondheim and George Furth musical Merrily We Roll Along in 1981; The Rink by John Kander, Fred Ebb and Terrence McNally in 1984; and the autobiographical Neil Simon play Broadway Bound in 1986.
