No because if they did, we would have heard something about it in the years since the film was made by the people who worked on it.
 
Cooper hated the gimmick of the man in an ape suit (which had been used in pictures as far back as the 1920's), and never wanted to even contemplate using that effect.in his "giant terror gorilla picture". So its highly doubtful that would be the case.
