Forgive me for going on a soapbox rant, but there are a few things on this subject. First of all, any actor who does this is not at all acting professionally. By yelling at an audience member, not only does your performance lack professionalism, but rather than focusing your energy on the dozens of people who paid to see the show, you're focusing it on someone who, as a result of their actions doesn't deserve the time of day.
I am far from a professional actor. I do theatre for the fun and the pleasure it gives me and nothing more. I have been in shows where there is a cell phone that goes off. You know what I do, I either have plowed through it or take a deep breath and continued. If amateur performers can do it, I don't see why professionals can't either. And, it's not like I have never been in a show where a cell phone went off. While I do feel that stories of cell phone usage in the theatre are embellished on here just a tad, they aren't without merit. I remember seeing a performance of Rabbit Hole on Broadway. During the last emotional scene, someone's phone started ringing. You know what Cynthia Nixon did? She continued. Of course, it should be worth mentioning that during the speech a the end for BC/EFA she said that the person who's phone went off should donate a little more. And, that got a little laugh from the audience. Point of my soapbox rand is that it does happen, but don't be a baby about it.
