Zooey Deschanel worries she doesn’t know how to act, femalefirst.co.uk reports.

She feels like a new and inexperienced actress every time she starts work on a new movie and struggles to gauge how well she has done.

She said: “That’s part of what makes acting so scary for me because like there will be total moments where I will be like, ‘I have no idea what I am doing.’

“Acting is not a quantifiable thing. You cannot put a number on it. You cannot be like, ‘OK I have done my 10 hours and my work is done.’”
