As The Big Bang Theory's eleventh season comes to a close next month, CBS has revealed the packed guest list for the season finale which will feature Sheldon and Amy's wedding.

Star Wars actor Mark Hamill, Kathy Bates (Misery), who won an Emmy for her guest appearance on Chuck Lorre's Two and a Half Men, and magician Teller will all be appearing in the episode though their exact roles have not been revealed.

As previously reported, we will be meeting another member of the Cooper family as Jerry O'Connell (Stand by Me, Sliders) appears as Sheldon's older brother, George Jr. Courtney Henggeler (Cobra Kai, Mom) will be reprising her role as Sheldon's twin sister, Missy, last seen in the Season 1 episode "The Pork Chop Indeterminacy", and Laurie Metcalf will be returning as Sheldon's mother, Mary.

An array of familiar faces will also be present with John Ross Bowie (Barry Kripke), Brian Posehn (Bert), and Wil Wheaton featuring in the episode. Lauren Lapkus, who first guest stars in this week's episode, "The Comet Polarization", will also be returning.

The eleventh season finale will air Thursday, May 10 at 8/7c on CBS. Don't panic though, The Big Bang Theory has already been renewed for a twelfth season to air in 2018/19.
