"We will try to maintain the essence and plot of the story as far as we can," it said in a Facebook post. Arbat, which translates from Thai as "violations committed by monks", was scheduled for nationwide release on Thursday.
Thailand's monks have come under increasing fire for their embrace of commercialism in recent years.
In April the Dhammakaya temple, one of the richest in the kingdom, returned about $20m given by a company executive later accused of embezzling the cash. Donations have long formed the bedrock of Thai Buddhism. Every morning barefooted monks make alms rounds in their local neighbourhoods while many devotees "make merit" by gifting money to temples.
The case of notoriously flashy monk, Wiraphol Sukphol, taking selfies while flying in a private jet triggered particular outrage. Other embarrassing incidents in recent months include a monk arrested for multiple sexual assaults, clergy dressed in civilian clothes drinking alcohol and crashing a car, and monks, who are expected to be celibate, having girlfriends.
