It's really happening! British theoretical physicist and cosmologist Stephen Hawking will finally make an appearance on an episode of The Big Bang Theory. According to TV Guide Canada, Hawking filmed a scene with the show's star Jim Parsons (Sheldon Cooper) on Friday and the episode is expected to air on April 5. This is exciting news for fans of the show since Hawking had previously been invited to guest star but then declined due to health reasons. The specifics of his role on the show are unclear, except that Sheldon has a run-in with Hawking, which subsequently leads to a hilarious back-and-forth between the two.
This news comes just after we learnt that another much-awaited guest star, Leonard Nimoy, will be lending his voice to the sitcom. Nimoy will appear on the March 29 episode as the voice of Mr. Spock in Sheldon's dream. Nimoy was last seen as a guest star on Fringe as Walter Bishop's former lab partner, William Bell.
