The Big Bang Theory has officially confirmed that actress Kathy Bates and magician Raymond Teller, of Penn and Teller fame, have been cast to play Amy’s parents during the Season 11 finale.\nAccording to an April 25 report by Entertainment Weekly, The Big Bang Theory fans will see a new actress step into the role of Amy’s mother. During Season 9, actress Annie O’Donnell appeared as Amy’s mother via a video chat. However, it will be Kathy Bates who really brings Amy’s overbearing mother to life.\nIn the past, Big Bang Theory fans have heard Amy describe her mother as being very overprotective, and giving her daughter a complex about nearly everything. Bates, along with Teller, will appear during the Season 11 finale, in which Amy and Sheldon will finally get married.\nKathy Bates is a widely-respected actress who has appeared in a plethora of fan favorite films and television shows. She’s best known for her roles in the Stephen King films Misery and Dolores Claiborne, as well as in movies such as Titanic, Fried Green Tomatoes, and more. She’s also become a fan favorite on FX’s horror anthology series, American Horror Story and guest starred on shows such as The Office.\nMeanwhile, Raymond Joseph Teller, or Teller as he’s more commonly known, is one half of the magical duo, Penn and Teller. The pair are widely known in the magic community. During their performances, Teller usually stays silent, not speaking at all, as Penn Jillette does all of the talking.\n\nThe Big Bang Theory: Amy's parents revealed! https://t.co/NWRmGxNkBZ\n— Entertainment Weekly (@EW) April 25, 2018\n\nHowever, Bates and Teller won’t be the only big names joining the cast for the huge finale event. Big Bang Theory viewers can expect to see Star Wars actor Mark Hamill guest star during the finale. Hamill’s role is being kept quiet, so it is unclear whether or not the actor is playing himself, or another member of the couple’s family. In addition to Hamill’s role, fans will also get to see Jerry O’Connell of Sliders cult fame as Sheldon’s big brother.\nOther former guest stars will also return for The Big Bang Theory’s season finale. Laurie Metcalf will reprise her role as Sheldon’s mother, Mary Cooper; Courtney Henggeler will return as Sheldon’s twin sister, Missy; John Ross Bowie will be back as Barry Kripke; Brian Posehn returns as Bert, and Wil Wheaton will also return as himself for the big wedding day episode.
