Tv Ad Voice Overs - Sounds Famous But Isn't

[hc4361]

Would an impersonator be allowed to voice over adverts deliberately sounding like a famous person?
For example, some personalities are perceived to be trustworthy, let's say John Noakes. He could very successfully endorse dog food or vet plans so could an advertising company do it on the cheap and use a sound a like without Noakes' permission or making it clear on the ad that it is not Noakes?

There is currently a nasty advert for a phone in competition that would appeal to the older person - a simple word search. The telephone call could cost £10 and the voice over sounds very like David Attenborough and wildlife is the theme of the competition. In this case, the voiceover man does introduce himself as 'Andrew, a wildlife enthusiast' but would it be legal if he didn't? Could Mr Attenborough sue?

[ummmm]

I doubt it if they make it clear it's not actually Sir David Attenborough.

Didn't Morgan Freeman have a similar issue with a voice over?

There have been quite a few ads with Joanna Lumley "soundalikes". Doubt if the celeb can do anything about it.
