Banks, who plays Alice Branning in EastEnders, showed off her look in this week's Now magazine.
"I'm having the best time ever," said Banks of her part in EastEnders.
"I'd auditioned before a few times - I first did one when I was 14 and then a few years later for the role of Lauren Branning.
"I knew at some point I was going to crack that nut."
Of her future career plans for the next five years, Banks said: "I'm not going to lie, I want to be in Hollywood by then. Do you think I can do it? Aim high, I say."
Asked whose Hollywood career she would like to steal, she added: "Kate Winslet's had a fantastic career and some great roles."
