Eva Mendez

Eva Mendez endured countless sleepless nights while making new comic book movie Ghost Rider, because the creepy film kept giving her nightmares.

The actress became so tired she called in a doctor to help her make it through the night. She says, "I was having nightmares at the end of this. I was in bad shape. I was immersed in this role."

"We were shooting nights, which is the entire night - until six in the morning when the sun comes up. I was in a bad space and it got a little creepy for me and I was having these awful nightmares. I remember seeing a doctor who told me I was freaking myself out."
