Megan Fox says 'Till Death' character was emotionally, physically draining: 'My adrenals were shot'

The "Transformers" actress plays a woman who awakens handcuffed to her dead husband and must fight off assassins.

"I was in every scene. I wasn't sleeping. A lot of stuff was going on here in the States, which is an opposite time zone. So I would be working all day in a really physical role and then getting very little sleep at night, maybe two or three hours. I did that for however many weeks, maybe five weeks," the actress explained to Fox News while promoting the film.  "When I got home, I was really exhausted and it did take me a minute to recover. Your body goes into this [mode] where your adrenals become completely drained because your adrenaline is constantly going [while filming]. I was exhausted. My adrenals were shot," she said.
