Becky Conner – Roseanne
The producers of Roseanne really confuse the fans, they didn’t switch actors once but multiple times. Lecy Goranson, a young actress played Becky Conner for the first 5 years of the series, was replaced by Sarah Chalke.
When Goranson decied to leave and go to college, the producers of Roseanne replaced her with Sarah Chalke, a known actress who stared in shows like Scrubs and Rick and Morty. And it didn’t end here, after some time, the producers of Roseanne brought back Goranson and had her switch with Chalke multiple times.
