Holmes is afraid of the dark

Frightened Katie Holmes was so spooked reading a script for new horror movie Don't Be Afraid Of The Dark, she had to turn on all the lights in her house.

The former Dawson's Creek beauty stars in Guillermo del Toro's latest grisly offering, in which a property is invaded by creepy monsters.

And the story is so terrifying, Holmes became convinced she could hear eerie noises in the home she shares with husband Tom Cruise while reading her lines.

The actress tells the New York Daily News, "When I read this script, I was scared and I had to turn on all the lights in my house. I thought I heard noises. And I held my child (Suri) really close."
