He's coming back to the future — as a guest star on Roseanne! Christopher Lloyd appeared in last night's episode as Lou, the boyfriend of Roseanne's mother. The actor will allegedly only appear in this one episode of the sitcom (although he's so beloved, we could see him continuing his stint on the show).
In the sneak peek for the episode, we get to see Christopher with Beverly (played by Estelle Parson). If you can recall from the original series, Bev divorced Roseanne's dad, Al Harris (played by John Randolph), after she learned he had a mistress for 20 years. He later died, but before his death, we learned he was abusive during Roseanne's childhood.
In the funny clip, Bev introduces Lou to Roseanne (played by Roseanne Barr) and Jackie (played by Laurie Metcalf). "These are my daughters," she says to him. Lou then tries to be funny with his reply, "I would have mistaken them for your sisters." To no surprise, Jackie has a comical response herself. "Uncalled for, Lou!" she exclaims.
The original Roseanne saw famed guest stars including George Clooney, Leonardo DiCaprio, Bruce Willis, Sharon Stone, Ellen DeGeneres, Debbie Reynolds, Tobey Maguire, and more. The reboot will also feature stars including Sandra Bernhard, Natalie West, James Pickens, Jr., and Adilah Barne.
In a previous interview, Roseanne Barr opened up about how Clooney didn't want to appear on the revival. "Well, George Clooney didn’t want to come on — so that was a bummer, but he lives in Italy," the 65-year-old shared on The Howard Stern Show. "He’s said some really silly things about me, but I still love him."
Even without Clooney, the reboot has already been renewed for a second season. "We're thrilled that America has welcomed the Conner family back into their homes," Channing Dungey, president of ABC Entertainment, said in a previous statement. "The show is as fresh and relevant today as it was when it left the air 21 years ago. We can't wait to see what the Roseanne team has in store for next year." We bet their ratings will go up even more with Lloyd on the cast now.
