The Price Is Right's most iconic host is Bob Barker - too bad he had to leave the show due to multiple lawsuits against him. In 13 years, Barker racked up nine different lawsuits from past cast and crew members, including a sexual harassment suit from former Price promo girl Dian Parkinson. She claimed Barker promised her job security on the show in exchange for sex. Although Barker has denied all the claims in every suit against him, he had no choice but to step away from the spotlight in 2007.
A sexual assault lawsuit between actors is never a good sign for a TV show. When Tisha Campbell filed her lawsuit against Martin costar Martin Lawrence, it meant that the two could no longer film scenes together - which proved difficult, since their characters were love interests. The awkward filming and disjointed plot lines led to low viewership and eventual cancellation.
According to Dustin Diamond's tell-all, "Behind The Bell" (a questionable source at best), the set of Saved By The Bell wasn't nearly as wholesome as you'd hope. Mario Lopez was apparently a hardcore womanizer, and at one point was accused of luring a girl back to his home and raping her. The victim had a strong case, so NBC execs paid her off to keep the story quiet and keep the SBTB cameras rolling.
David Yost is the actor who played Billy the Blue Ranger on the Mighty Morphin' Power Rangers TV show. He walked off set one day in the '90s, saying, "I was called f*ggot one too many times." Producers of the show were supposedly digging for information on Yost's sexual orientation (Yost has said, "I know that my costars were called in a couple times to different producers’ offices and questioned about my sexuality, which is kind of a humiliating experience to hear that") and Yost walked out before things escalated. Producers tried to get him back for the reunion show, but Yost stayed strong.
