From my friend, Lauren Yarger, who reviews Broadway plays from a Christian perspective (http://reflectionsinthelight.blogspot.com):
Subject: picking your brains Hi! I am researching a project and am gathering opinions about which Christian vocal artist people would most like to see star in a regular Hollywood film (singing is required of the actor). Could you send me your ideas of who might be the biggest box office draw? If possible, could you ask your readers to let us know what they think? There's a poll on our blog at http://www.facebook.com/l/5c61f;christianperformers.blogspot.com/ or they can email us at email@example.com.
Thanks for your help.
