Oscar replaces Kevin Chamberlin as the ghoulish and charming Fester in the musical comedy inspired by macabre characters created by illustrator Charles Addams. The show plays Broadway's Lunt-Fontanne Theatre.

Also starting March 8: Heidi Blickenstaff (as outsider Alice Beineke, created by Carolee Carmello), Adam Grupper (as starchy husband Mal Beineke, created by Terrence Mann), Rachel Potter (Wednesday, created by Krysta Rodriguez) and Jesse Swenson (Lucas Beineke, Wednesday's "normal" new boyfriend, created by Wesley Taylor).

Nathan Lane and Chamberlin, Carmello, Mann, Rodriguez and Taylor left the show March 6, at the end of their contracts. Merwin Foard, the production's standby for Lane's Gomez, plays the patriarch of the clan until March 22, when Tony Award winner Roger Rees (Nicholas Nickleby, "Cheers," "The West Wing") steps into the part.

Continuing in the roles they originated are Tony winner Bebe Neuwirth as Morticia, Zachary James as Lurch, Adam Riegler as Pugsley Addams and Jackie Hoffman as Grandma.

The Addams Family features a book by Marshall Brickman and Rick Elice, and music and lyrics by Andrew Lippa. The production is directed and designed (sets and costumes) by Phelim McDermott and Julian Crouch, with creative consultation by Jerry Zaks and choreography by Sergio Trujillo.
