Matt Atchity, editor-in-chief of the Rotten Tomatoes film review website, crafted "10 Commandments for Movie Audiences" including "Thou shalt not text." But the ubiquity of cell phones makes these sensible suggestions hard to enforce.
"Even 10 years ago, not everyone had a phone, not everyone was text messaging. The younger generation grew up and the kids who were texting in class are now the kids who are texting in movies," Atchity said.
He added that Hollywood's focus on the 18-24 demographic is also a factor. "A big opening release is like going to Chuck E. Cheese," Atchity said.
While adults might believe what's on screen deserves their full attention, kids nowadays view the movie-going experience as interactive, said Bill Goodykoontz, film critic for The Arizona Republic and father of four.
"They can't imagine seeing anything, including a movie, without immediately supplying their reactions," said Goodykoontz, who's also chief film critic for Gannett.
Producer Barry Mendel ("Bridesmaids") believes the reliance on social media and 24-7 information has bled into every part of our lives — even places that are meant to provide an escape.
"It's very rare in our society to sit and stare at something intensely and without distraction for two hours. People just don't have that muscle anymore," said Mendel, a two-time Oscar nominee for best picture for "The Sixth Sense" and "Munich."
"It makes me worry for my profession, for making movies," he continued. "In order for a movie to be good, someone needs to sit down and read a screenplay and help the writer make it better. Instead they start reading a script, then they stop reading it and pick it up later."
Rachael Harris ("The Hangover," ''Diary of a Wimpy Kid") said a guy recently walked in late to a private screening of the new independent film she stars in, "Natural Selection," sat down next to her and immediately checked his BlackBerry.
"As an actor, you do have a sense of: 'How dare I not be riveting enough that you have to check your email?' You react personally but then you realize it's not personal. It's just bad manners," she said.
But many of the young people who engage in these practices don't think it's a problem because everyone does it. Thirteen-year-old Will Barnes of Frisco, Texas, says he texts sometimes during movies, but tries to be courteous.
"I didn't really like 'Thor,' so I just pulled out my phone and texted a little bit. It was during the day so nobody was really in the theater at the time," Barnes said. "I'm just looking at the screen, I'm not paying attention to what other people are doing. But you see adults doing it and I think it's a little immature for their age to be texting during a movie."
Fourteen-year-old Andrea Lopez of Newhall, Calif., says she leaves her phone on during movies but keeps it on silent: "Normally I'll just text during the end of the movie to have my mom or dad come pick me up."
But when others are blatantly using their phones, Lopez said, "that's ridiculous. Then they're just ruining the movie for everyone else. The least they can do is go outside and talk."
But not all offenders are adolescents: "I am the worst. It annoys my kids," said Tracy Tofte, a 40-year-old real estate agent and mother of two in Santa Clarita, Calif. "If it's a slow part of the movie I can't help looking at my phone and going, 'Oh, I have an email.'"
Theater owners have tried a variety of methods to get folks to keep quiet and stay off their phones, from showing amusing messages beforehand to having ushers sweep through the auditorium during the show, said John Fithian, president of the National Association of Theatre Owners. Some have experimented with dividing moviegoers into over-21 and under-21 auditoriums, but that can get disorganized.
"It's an educational process but we and our members and the people who write about our industry know that the beauty of cinema, first of all, is that it's a shared experience. That means there are shared responsibilities," said Fithian.
