Stars from Garry Marshall's beloved sitcoms to appear on 'The Odd Couple'

LOS ANGELES, Oct. 31 (UPI) -- Happy Days veterans Ron Howard, Marion Ross, Anson Williams and Don Most are to appear on an upcoming episode of The Odd Couple, CBS announced.

Also expected to pop up on the star-studded, Nov. 7 edition of the show are Penny Marshall and Cindy Williams from Laverne & Shirley, and Pam Dawber from Mork & Mindy.

All of the actors saw their careers skyrocket on shows created by the late Garry Marshall, who developed and was the executive producer of the original television version of The Odd Couple, and served as executive consultant on the current incarnation.

Marshall played Oscar's father, Walter, in the remake, as well. He died in July at the age of 81.

Next week's installment will pay tribute to Marshall by showing Oscar [played by Matthew Perry] as he reconnects with significant people from Walter's life while attempting to realize his father's final wish to have his ashes spread behind the candy factory he used to own.

"The writing staff and everyone on The Odd Couple reboot was thrilled when Garry Marshall joined us as a producer because his shows were part of our TV DNA," executive producer Bob Daily said in a statement Monday. "He was a kind, generous presence on the set, and we loved him dearly. And when we lost him, we knew we had to do something to honor his legacy -- something that, like Garry's work, was both heartfelt and zany. We are so grateful that the stars of these classic shows are able to join us in honoring him."
