Gwyneth Paltrow ran into some obstacles while trying to identify with her character in Country Song.

"I just couldn't understand how you could be so drunk that you could wreck people's lives and then wake up the next day and pretend everything was fine," she said.

Gwyneth revealed how she prepped for the film in a recent interview.

Paltrow wanted real insight into addiction, and how it affects the user as well as those around them. So, she went to someone with real life experience: Iron Man co-star Robert Downey, Jr.

“He was really articulate about addiction and the psychology behind it. He really helped me a lot.”
