Christina Hendricks battled nerves working with Ryan Gosling

Christina Hendricks battled nerves and anxiety after Ryan Gosling approached her to star in his directorial debut How To Catch A Monster.

The Mad Men beauty previously worked with Ryan Gosling on 2011 crime drama Drive, but admits she felt intimidated about being one of the leading ladies in his upcoming sci-fi thriller.

She tells Canada's Flare magazine, "(Gosling) called me and asked me if I was interested in doing this film and I said: 'One, of course, yes, and two, why me? And three, I don't want to disappoint you.'

"He's been fantastic, involving me artistically and letting me be along the road of casting and costume design. I've seen story boards and imagery and I've heard music. It's the largest role I've ever had, so this is one I'm definitely aware of my anxiety about."

While Christina Hendricks' Mad Men co-stars have become "like family", the redhead still feels apprehensive about working on movie sets.

She adds, "Every time you do a film it's like the first day of school. You don't know what the kids are going to be like; you don't know what your environment is going to be like. The first-day jitters that everyone gets last a little longer for me."
