Their letter cautioned that the public was increasingly aware of and disgusted by the psychological and physical abuse inherent in forcing a chimpanzee to "act".
Pointing out examples of graphics used in films like Jungle Book and Planet of Apes, PETA said, "forward-thinking filmmakers and directors know that the future of film lies in technical wizardry, not in beating animals into performing."
"Eyewitness investigations have revealed that trainers often punch, kick, beat, and even electrically shock apes during behind-the-scenes training sessions and on set in order to ensure that they perform correctly in the fewest takes possible," Sachin Bangera from PETA said in the letter, also marked to Prasoon Joshi, Chairperson, Censor Board of Film Certification.
"We've matured as an industry and realised that [using real great apes in film] would be intolerable and cruel," the letter said.
