The Big Bang Theory's "Shamy" wedding episode has a big guest list.
The two movie stars have signed on for special guest spots in the sitcom's current season finale, which revolves around the nuptials of Jim Parsons and Mayim Bialik's characters Dr. Sheldon Cooper and Dr. Amy Farrah Fowler. It's unclear what roles any of the new people will be playing, but Hamill's inclusion is a big get for the show given the gang's obvious love of "Star Wars" and the actror's renewed popularity thanks to his starring role in "The Last Jedi".
Making the lengthy list are American Horror Story's Kathy Bates, Mark Hamill (Star Wars), Teller of Penn & Teller, John Ross Bowie (Speechless), Lauren Lapkus (Crashing), Courtney Henggeler (Cobra Kai), Brian Posehn (Steven Universe), and Wil Wheaton (Stand by Me).
This will mark Hamill's first appearance on the hit CBS show, but he won't be the first newcomer to make a guest appearance in the season finale.
At PaleyFest in March, a Big Bang producer said O'Connell would play Sheldon's brother, Georgie.
It is not known whether Hamill will play himself, as Fisher and Earl Jones did.
Looks like most of Sheldon's family will be in attendance for his wedding, but we haven't heard much of whether Amy's family will be there.
The season finale of The Big Bang Theory will air on 10 May.
