Oh the irony. She starred in a hit autobiographical stage play, Joan Rivers - A Work In Progress By A Life In Progress, in which the 75-year-old Rivers danced the hora in celebration of getting her most hated foe, an ageist TV executive, sacked by falsely accusing her of antisemitism. Now Rivers has had to cancel the December return of her play because... a TV executive has unexpectedly given the go-ahead for her new sitcom. A case of life contradicting art.
