Katee Sackhoff

Katee Sackhoff portrayed only an imaginary version of herself. Yet she credited the series for helping her discover her comedic abilities. In an interview, Sackhoff said, "[The show] really... helped me decide that I could do [comedy]." Her enthusiasm led to her eagerly accepting a second episode.

Bob Newhart

Bob Newhart's guest appearance as Sheldon's childhood hero resonated with the cast and audiences alike.

Adam West

Known for portraying Batman in the famed 1960s series, West was also eager to appear in the show. He told Variety, "For years, I thought, oh, they're just ignoring me. They don't want me around. And then I find out that they waited for the 200th-anniversary show, knowing, I think, too, that it's Batman's 50th anniversary."

Mark Hamill

Mark Hamill made a lasting impression, according to showrunner Steve Holland, who remembered his laid-back demeanor, spending hours with the writers and cast.
