Allison Williams is a "perfectionist".
Allison Williams says she is like her character Marnie in that they are both perfectionists.
The 25-year-old actress can see some similarities between herself and her 'Girls' alter ego Marnie, though she insists she is trying to be more relaxed.
She said: "Marnie is a perfectionist and so am I. Playing her, I can see how it's perfectionism and pride that prevents her from getting any peace.
"I would call myself a perfectionist too - although I've let go of trying to be perfect. Will Marnie get where she wants to get to? I hope so."
Allison also admits she often feels uncultured next to her co-star, the show's creator Lena Dunham, because her influences are so vast.
She said: "Lena Dunham is an 'old soul'. Her cultural references are from way before she was born.
"They make me feel like I've never watched a film in my life. She has a wisdom and a gentleness to her."
Allison promised the new series of 'Girls' will allow fans to understand her character more, thanks to the introduction of her mother, who is played by Rita Wilson.
She told Britain's Grazia magazine: "We understand Marnie's character more clearly after meeting her mother. There's a sense of, 'Oh that's Marnie's mum. That's why she's so crazy!'
"This is supposed to be her support and her mum is a nightmare. I think until Marnie realises there's a problem and she needs help, she's in trouble."
