Davies, who was born in Swansea, said he would like the Welsh actress to star in a big screen adaptation of the cult BBC show.
He said: "Being from Wales myself, I would love to have Catherine Zeta-Jones as a companion for The Doctor."
Davies, 45, added that he can only imagine current Doctor David Tennant as the Time Lord, saying: "To have anyone else would be inconceivable."
Tennant is rumoured to be keen to sign a new deal with the BBC which commits him to a fifth series of the show and a spinoff movie.
