The 20-year-old is currently best known for her role as Charlotte Hinchcliffe in E4 comedy The Inbetweeners and for her weekly performances on the latest series of Dancing On Ice.
Speaking to The Mirror, Atack explained: "I'm dying to do a drama. I want a part playing a really ugly geek, with no make-up and my hair all tied back so I could just be a character without worrying how I look."
However, the star said that her future acting ambitions will remain on the backburner "for the moment" while she concentrates on Dancing On Ice.
She added: "I'm never going to be the best skater, but I feel like I'm getting better. My partner Fred Palascak is great, he's made the experience much more fun."
