Reunion shows planned for ‘Dallas,’ ‘One Day’

Dipping deeper into its vaults, CBS has come up with two more reunion specials for next season.

The cast of “Dallas” will return to the show’s Southfork Ranch to reminisce about the seminal prime-time soap, while the stars of “One Day at a Time” will also look back at their time on the network.

Reunion specials have been reliable ratings magnets for CBS in recent years.

A “Carol Burnett Show” reunion in 2001 drew close to 30 million viewers, surprising just about everyone in the TV business and paving the way for a spate of similar shows.

Last week, another “Carol Burnett” special and “The Dick Van Dyke Show Revisited” delivered 13.6 million and 14.6 million viewers, respectively, to CBS. Both were in the Nielsen Top 20 for the week.

A “Dallas” reunion seems like a natural. The series, which ran from 1978-91, was the No. 1 or No. 2 show on television for five straight seasons in the ‘80s, and the 1980 episode in which viewers learned who shot villain J.R. Ewing (Larry Hagman) — it was his mistress, Kristin Shepard (Mary Crosby) — is one of the most-watched programs of all time.

“One Day at a Time” doesn’t immediately come to mind as a classic sitcom, but it was a Top 20 hit for pretty much its entire nine-season run. Stars Bonnie Franklin, Valerie Bertinelli, Mackenzie Phillips and Pat Harrington will come together to look back at the show, aided by a heavy dose of clips.
