Michael Sheen has blasted critics who recently claimed he is simply an "impressionist".
The Welsh actor is currently portraying Brian Clough in The Damned United, which focuses on the legendary football manager's tenure with Leeds.
However, previous roles as Richard Nixon and Tony Blair have led some to claim that he is simply impersonating the famous figures he plays.
"It's wrong. I hope people will be able to think about it a bit more and see it's not an impression. I don't do impressions," he told the Guardian.
"With absolutely no disrespect, give the script of The Queen or Frost/Nixon or Damned United to Rory Bremner or Alastair McGowan and let's see. But likewise I could try to do what they do and I would look a t**t because I can't do it."
Sheen recently claimed that he hopes the family of Brain Clough will go and see the film, which is released in the UK on March 27th.
