David Hasselhoff, who begins as Broadway's Jekyll & Hyde beginning Oct. 17, will appear at the Plymouth Theatre box office Sept. 25 from noon to 2 PM.

The TV star and pop singer will mingle with fans and ticket buyers and chat with media. The first 100 people in line will receive a special gift.

Oct. 31 has been marked as the official opening for the bewigged Hasselhoff, who, like the current star, Sebastian Bach, will play six shows a week. Rob Evan, a past favorite in the roles, will return to the show to play matinees beginning Oct. 4.

After opening in 1997, the pulpy musical by Leslie Bricusse and Frank Wildhorn has yet to recoup its $7 million investment, but is an audience favorite, especially for rabid fans who call themselves "Jekkies."

* Hasselhoff, 48, the singing star and hairy hunk from TV's "Baywatch" and "Knight Rider," makes his Broadway debut with the show. The actor-producer is internationally known for the syndicated eye-candy lifeguard series, "Baywatch" and "Baywatch Nights." Hasselhoff's pop singing is a sensation in Europe, where his fans clamor for his concerts.

The casting of Hasselhoff had been rumored for months. Before Bach, pop singer and soap star Jack Wagner was the previous star of the bloody show.

Beyond being known for the standout tune, "This is the Moment," Jekyll & Hyde is remembered for its much parodied transformation of Dr. Jekyll to evil Mr. Hyde, which requires the actor to shake out a long mane of hair to suggest the character's chaotic nature.

For the record, Wagner was wigged, Bach is not and Hasselhoff will also get a fake hairdo.

The Plymouth Theatre is at 236 W. 45th St., between Broadway and Eighth Avenue.
