Interested in theater, Pierre Hatet attended classes at the Center of Dramatic Art before entering the Conservatory.

In dubbing, he was the regular French voice of Christopher Lloyd, notably in the Back to the Future saga, in which his performance as Emmett Brown has become very famous in France. He was also the voice of the message in the Mission: Impossible series between 1966 and 1973.
