Adisak Wannasin, president of the Buddhism Relations Association, said his association and the Network of Buddhist Organisations want the Nak Prok movie to be banned.
The movie is scheduled to be screened on Thursday.
It is a movie about three robbers who disguise as Buddhist monks to try to get the money they hid inside a temple compound but a temple hall was later built on the ground they buried the money.
Adisak said the movie was sensitive and could damage Buddhism's image.
