‘Mary Tyler Moore’ Cast to Reunite on ‘Hot in Cleveland’

Terminally ill Valerie Harper to join Mary Tyler Moore, Cloris Leachman, Betty White and Georgia Engel on upcoming episode

"Hot in Cleveland" is hoping its new casting gimmick will turn the world on with a smile.

Mary Tyler Moore ShowThe TV Land hit, which was recently renewed for a fifth season, is staging a reunion of "The Mary Tyler Moore Show" cast for an upcoming episode, with Mary Tyler Moore, Cloris Leachman and the ailing Valerie Harper (all in photo at left) joining forces with "MTM" alum and "Hot in Cleveland" star Betty White and recurring cast member Georgia Engel.

The episode, which does not yet have an air date, will focus on Elka (White) and Mamie Sue (Engel) reuniting their bowling team GLOB: the Gorgeous Ladies of Bowling. The team, which fell apart decades earlier after its championship season led to swollen egos, includes members Diane (played by Moore), Peg (Leachman) and Angie (Harper).

Moore has guested on "Hot in Cleveland" before, playing Elka's cellmate in the show's second season.

Harper, who played Rhoda Morgenstern on "The Mary Tyler Moore Show" and the spinoff "Rhoda," announced earlier this month that she has brain cancer and might have as little as three months to live. Leachman played resident busybody Phyllis Lindstrom on "The Mary Tyler Moore Show," which ran on CBS from 1970 to 1977.

Unfortunately, Chuckles the Clown was unable to make it for the reunion, having been tragically killed by a rogue elephant while dressed as Peter Peanut in a circus parade.
