Leonard Nimoy will appear in an upcoming episode of ‘The Big Bang Theory’ – but maybe  not in the way fans had hoped.

After announcing his retirement last year , actor Leonard Nimoy has agreed to appear on  CBS’s hit series The Big Bang Theory – well, sort of.

On March 29th, the sci-fi-legend will appear in an episode during one of Sheldon’s  dreams. Unfortunately, Nimoy’s cameo comes with one slight hitch: we won’t actually see  him onscreen. Instead, Nimy’s appearance will be following in the same vein as his other  recent roles, with the actor appearing via voice-over only.

The Big Bang Theory DVD is hot on sale on Cheap DVD Shop.
