This may stretch the definition of “celebrity” or “well known person” but when I hear Mayor of Detroit Mike Duggan speak he sounds a lot like Bob Odenkirk to me.
I was half-watching Life of Crime over the weekend, and kept thinking that I heard John Goodman’s voice. Nope…it was Mark Boone Junior, who played Bobby Elvis on Sons of Anarchy. I never thought he sounded like John Goodman before, though.
Anthony Hopkins pretty famously dubbed Laurence Olivier’s lines for the restored scenes in Spartacus back in 1989 (or thereabouts). The footage still existed, but the soundtrack was damaged. Tony Curtis was still alive to re-dub his dialogue, but Olivier had passed on. Someone recommended Hopkins, because he had shown he could do a great Olivier.
If I hadn’t been told he did it, I never would have guessed. It’s a great imitation – not exaggerated or extreme.
Vincent d"Onofrio played Orson Welles in Ed Wood and in Five Minutes, Mr. Welles. He looks pretty close to the part (properly lit), but his voice is a good imitation, too.
I gotta take exception to this. Although they were fine singers, they had distinctive voices. There’s no way you would confuse Bing Crosby’s deep scoop with Dean Martin’s easy glide. I can imagine Dino singing “White Christmas”, and it wouldn’t sound anything like Bing’s version.
Personally, I think William Daniels (voice of KITT, principal on Boy Meets World) and William Powell (movie star of '30s and '40s) sound almost identical.
Another one is Craig Stevens, the guy who played Peter Gunn in the 1950s TV series, sounds quite a lot like Cary Grant, although I suspect there is some conscious mimicry involved.
“Nobody talks like that!”
–Jack Lemmon, in * Some Like It Hot, *, mimicking Tony Curtis’ high-tone accent, that Lemmon had used for his rendezvous with Marilyn Monroe. (Cary Grant himself had a similar reaction when he saw the movie.)
