Roseanne Barr wants to come back to TV comedy. Sources say the former sitcom star has set up a new project at 20th Century Fox Television with her longtime boyfriend, Johnny Argent. The project, titled “Downwardly Mobile,” would be an acting vehicle for Barr. It’s designed to mine similar territory to her hit 1990s sitcom “Roseanne”: a close-knit, blue-collar family living in tough economic times.It would be Barr’s first sitcom since “Roseanne” ended in 1997 after nine seasons. The Emmy-winning actress also dabbled in the talk show world with “The Roseanne Show” and now appears on the Lifetime docu-series “Roseanne’s Nuts.”
