Travolta Lands 'Fat' Guest Role

Look who's joining Kirstie Alley.

The former "Cheers" actress will be accompanied by John Travolta, who was featured with Alley in the "Look Who's Talking" films, in her upcoming show on U.S. cable television.

The seven-episode, unscripted comedy series titled "Fat Actress" won't debut until March, but cable network Showtime has revealed several guest stars slated to step inside Alley's hyper-reality world.

In the series, Alley plays a fictionalized version of herself, a TV and movie actress whose growing weight problem has been well documented in supermarket tabloids.

"She was thinking of something she could … do creatively for the second part of her career," People magazine editor Jess Cagle explained this summer on CBS News' The Early Show. "She thought, 'Well, I have a weight problem, and people are obsessed with that.' So she created this TV show, 'Fat Actress.' She basically plays herself, a celebrity, running around Hollywood."

Each episode emanates from a story outline with the actors largely improvising the dialogue.

NBC Universal TV Group President Jeff Zucker, Mark Curry and Travolta's actress-wife, Kelly Preston, also will guest star on the first episode, Showtime announced last week.

Alley played sassy bar manager Rebecca Howe on the '80s sitcom "Cheers," and later starred in "Veronica's Closet" for three seasons. Her "Cheers" co-stars may also appear in the new series.

Besides the "Look Who's Talking" movies, her films include "For Richer or Poorer" and "Deconstructing Harry."

Alley, 53, also served as the celebrity spokesman for furnishings outlet Pier 1 Imports for three years.

"When you're with her, she looks heavy, but she looks healthy. Most of all, she looks happy. This is a woman who laughs really, really easily," said Cagle. "I think the big change in Kirstie is — while she doesn't like the way that she looks; she does plan to go on a diet eventually — she also has never been happier with herself than right now."
