Stephen Hawking Spoof Auditions Celebrities For His New Voice

Stephen Hawking is on the hunt for a new voice.

Well, not really. But that’s the premise of a hilarious spoof clip that aired Friday in the United Kingdom as part of charity Comic Relief’sRed Nose Day.

Having used the same computerized tone for three decades, the famous British physicist decides he’s ready to switch it up — and auditions celebrities for the “once-in-a-lifetime opportunity.”

Actors including Stephen Fry, Liam Neeson, Anna Kendrick, Rebel Wilson and Lin-Manuel Miranda do battle over the role. Foul-mouthed chef Gordon Ramsay puts in a curse-filled appearance. Even Eddie Redmayne, who won an Oscar for his portrayal of Hawking in the 2014 movie “The Theory Of Everything,” has a go.

But ultimately, there’s only one winner — as Hawking opts for one of Hollywood’s most recognizable voices.

Check out the full clip above.
