WATCH: Stephen Hawking Hilariously Auditions a Slew of A-List Stars to Find a New Voice

Liam Neeson, Anna Kendrick, Rebel Wilson and more auditioned to replace Hawking's iconic computerized voice as part of a new Red Nose Day sketch

Stephen Hawking is looking for a new voice — and a slew of A-list stars want in on the gig.

Liam Neeson, Anna Kendrick, Rebel Wilson and more auditioned to replace Hawking’s iconic computerized voice as part of a new Red Nose Day sketch.

“Time to find my new voice,” Hawking says in the clip.

First up: Neeson.

“Stephen, it’s me, surely it has to be me,” the Taken star says in his audition reel. “Listen to my voice. It’s deep, it’s sexy, it’s got a tinge of … physics.”

And while both Wilson and Kendrick said they felt they could relate to Hawking’s level of intelligence, Lin-Manuel Miranda pulled out his rapping skills to try to impress the famous physicist.

“Yo my name is Lin-Manuel and my voice is dope as hell,” the Hamilton star raps. “So you’re Stephen Hawking from Cambridge college, but your voice is mad robotic if I’m being honest.”

Eddie Redmayne, who took home the Oscar for his portrayal of Hawking in the film The Theory of Everything, sent in his tape — though he was a little annoyed that he even had to audition.

“So what is it, like a sequel?” he said. “If they want me to go through that again they’re going to have to pay me a s—load of cash.”

Hawking’s decision? You’ll have to listen to find out!

The celebrity-studded Red Nose Day, which is mounted by Comic Relief, airs live on BBC One in the U.K. on Friday night, and will air in the U.S. on May 25 on NBC.
