Tony-winner and long time cast member, Ron Rifkin will be leaving Broadway's Cabaret. Though no replacement has been announced, Rifkin's last performance will take place May 2.

Rifkin has played his Tony-winning role Herr Schutz, since the revival's Broadway debut in March 1998. He was originally announced for the cast of the then Broadway-bound, Proposals by Neil Simon. His other Broadway roles include A Month In The Country and Broken Glass, though his break-through roles were Off-Broadway in the Baitz dramas The Substance Of Fire and Three Hotels.

Another Cabaret Tony-winner, Alan Cumming will play his final performance as the Emcee of Broadway's Cabaret June 6. No official replacement has been announced for his role either, though a spokesman for the production denied rumors that Lea DeLaria had been considered for the part.

Cumming, who had taken numerous leaves of absence to appear in Julie Taymor's film adaptation of Titus Andronicus, will be leaving Cabaret for good to begin work on another film -- the sequel to 1994's live-action "Flintstones," dubbed "Viva Rock Vegas." Cumming will play The Great Gazoo, the green martian who doles out advice to Fred and Barney. Though the initial live-action "Flintstones" film starred John Goodman, Rick Moranis, Elizabeth Perkins and Rosie O'Donnell, none of them will reprise their roles in "Rock Vegas."

Other film credits for Cumming include: "Goldeneye," "Romy and Michelle's High School Reunion," "Emma," and "Circle of Friends." The Scottish actor originated the emcee role for director Sam Mendes' "environmental" setting when the production premiered at England's Donmar Warehouse.
