If it's something I really care about watching, like Mad Men, I'll solely focus on that, I have subtitles on, that's all I'm focusing on because I don't want to miss a single line.
Of course I never pull my phone out at the movies, I put it on do not disturb.
But if I'm watching a movie at home I usually have subtitles on and I'm pretty good about not looking at other things but I have a bad habit of pulling out my phone or pausing to go read the Wikipedia page of the movie I'm watching, the director page, the actor page etc. Then after I read Wikipedia I'll go and read the imdb trivia page, then I'll go to RogerEbert.com to see what Ebert was saying, then I'll go to rottentomatoes, then I'll search for the movie on the AV Club website....
Next thing you know I've paused the movie for 30 minutes, a 90 minute movie can take several hours around my parts
