Cinema staff in the US are being offered up to $500 (£275) to catch people recording movies on camcorders.
The reward scheme is being run by film studios and movie theatres in a bid to stop piracy, which costs the industry billions of dollars each year.
Staff can qualify for the reward by catching the perpetrators, telling police and stopping the recording.
Other anti-piracy moves include staff wearing night-vision goggles to see if customers are recording films.
The Motion Picture Association of America (MPAA) said it seized 52 million DVDs and other illegal copies of movies in 2003 - many of which began as recordings made in theatres during the first few days of a movie's opening.
Metal detectors
Hollywood studios have already cracked down on tapings made during pre-release screenings.
Studios often search bags and use metal detectors to catch people taking camcorders into the screenings.
Studios have also been lobbying for state laws that make recording a movie in a theatre a crime.
In California, individual theatregoers can make a citizen's arrest of someone recording a movie.
The reward programme is co-sponsored by the National Association of Theater Owners and MPAA.
