From Cinemas mull cell phone ban:
“With theatergoers on the edge of their seats, the film reaches its climax as the villain turns to the hero and utters his last words, which cannot be heard over the unexpected, annoying ring of cell phone.
Such disturbances could become a thing of the past. The motion picture industry is considering implementing technology designed to block or restrict cell phone reception in cinemas.

Most movie theaters have on-screen reminders and lobby signs asking customers to silence their cell phones. Wireless provider Cingular even sponsors pre-film ads to encourage proper etiquette.
Parents with young children may want to stay connected to baby sitters in the event of emergency. Doctors on call would also need to be reachable.
“Their right to go to the movies on call ends at the tip of my ears,” said Joseph Tecce, a psychology professor at Boston College. “Cell phones have created and nurtured a greater atmosphere of entitlement.”"
Seriously, it’s not hard to remember to turn off your cell phone when you go to a movie. With all the signs and advertising around, some people just don’t get it. Just put your phone on vibrate if you don’t want to miss a call!
