Merrick Morton / Columbia Pictures
The character: Meg Altman, a wealthy, recently divorced woman who is spending her first night with her teenage daughter (Kristen Stewart) in a massive Manhattan brownstone complete with a so-called panic room
The peril: Home invader Burnham (Forest Whitaker) has heard of tales that the former owner hid millions of dollars in the house, so he brings his partners (Jared Leto and Dwight Yoakam) with him to get in, find the money and make a quick exit. They have no idea that there is anyone in the house. Resilient Meg protects herself and her daughter with the veracity of a mother grizzly against the three squabbling robbers. Guess who wins? Coincidentally, Foster was pregnant during the film's production.
