BEIJING, April 26 -- Oscar-winner Robin Williams and John Travolta have reportedly signed on to star in a Disney comedy, "Old Dogs."

The buddy movie tells the story of old friends whose lives are turned upside down when they find themselves responsible for seven-year-old twins, Variety reported.

The film, directed by Walt Becker, also was to feature Travolta's daughter, Ella Travolta.

Travolta, 53, was a ladykiller in "Saturday Night Fever," just a killer in "Pulp Fiction," and is now hoping to kill at the box office as a transvestite in the silver-screen adaptation of the musical "Hairspray."

Williams, 55, took home a best supporting actor Academy Award in 1998 for "Good Will Hunting," and recently starred in "RV," "Happy Feet," "Man of the Year" and the upcoming "License to Wed."
