TORONTO — One of the more impossible debates in the world of commercial cinema is how to deal with cell phones in movie theaters. Cinephiles, purists, and the Alamo Drafthouse Theater chain say ban them completely, and yet more casual moviegoers and busy humans continue to whip out the iPhones and Androids as the picture rolls. Man versus technology, the past versus the future, art versus commerce: this dilemma has it all. But will there ever be a resolution?

One vigilante at the Toronto International Film Festival decided to take the situation into his own hands... and that of the police.

Alex Billington, the proprietor of the movie blog Firstshowing.net, was particularly aggrieved by an audience member using his cell phone during a Press and Industry screening of director Ti West's horror flick The Sacrament on Monday, leaving the theater and dialing 911 to report the offender. Cell phones are often used during these screenings, with industry members ducking in and out of different movies for appointments and other matters, and Billington had had enough of the scourge of little lights interrupting his viewing.

After dealing with the police and festival higher-ups, he took to Twitter to explain the situation and lead a charge against the second screen menace.
