The former Guiding Light and Dynasty star portrays "a former Hollywood star who's on her way to crash her ex-husband's funeral with a friend, played by Pauline Collins."
Variety does not indicate when The Time of Their Lives will be available for American audiences.
Collins' recent appearances include a TV role in The Royals (Grand Duchess of Oxford) and a cameo in the recent cult favorite Absolutely Fabulous: The Movie.
The Royals returns to E! for its third season in December.
