The voice of Paris
Jacques Sernas' lines were dubbed by a British actor -- Geoffrey Toone ( he appeared in many films including THE KING AND I)
It was not done by Edmund Purdom although someone has that posted here and IMDB should remove it or correct it. Purdom's voice was well known in 1956 and unlikely to be used for another actor( but not impossible).
You can hear Sernas doing one of his own lines on the trailer that is on the WB DVD.
