Check out Miss Stewart before she was in Twilight!

When Kristen Stewart was just 12 years old she starred in the scary film Panic Room!

Look how different she looks...

Kristen plays Sarah Altman, a girl whose parents are going through a divorce. Along with her mum, they move into a new house where the previous owner had a panic room installed - a room so secure that noone can get in.

When three burglars break in, Meg makes a move to the panic room. But all her troubles don't stop there. The criminals know where she is, and what they require the most in the house is in that very room.

Check out the trailer here:

Did you know that Kristen was in this film? Have you seen it?

Make it the next dvd you rent but make sure you've got a boyfriend or pillow to hide behind for the jumpy bits!
