Another star from a galaxy far far away will be making an appearance on CBS’ hit comedy series The Big Bang Theory

Star Wars’ Mark Hamill will be among the guest stars confirmed for the upcoming Season 11 finale of Big Bang, which will feature the wedding of Sheldon and Amy. It is unclear whether, like fellow Star Wars icons Carrie Fisher and James Earl Jones who had appeared on the show before him, Hamill will play himself.

Also guest starring in the finale, airing on May 10, is Kathy Bates. Sheldon’s family will be well represented, with Laurie Metcalf, Courtney Henggeler and Jerry O’Connell, who play his mother Mary, twin sister Missy and older brother Georgie, respectively, all in attendance.

Also on the guest list for the finale are recurring Big Bang actors John Ross Bowie and Wil Wheaton as well as Lauren Lapkus, Brian Posehn and Teller.
