The 32-year-old actress stars as a "punk rock" porcupine named Ash in the upcoming animated musical comedy, and expects two-year-old Rose - whom she has with journalist husband Romain Dauriac - would be "overwhelmed" by the tale, though she still may show it to her as it is the "only movie" the blonde beauty has made that is child friendly enough for her tot.

Speaking to E! News, Scarlett said: "I'm sure she (Rose) would probably freak out. It would blow her mind.

"I'm not sure, she's pretty young so I imagine everything in her mind is a little bit sort of trippy to begin with. So I think just seeing my voice coming out of a porcupine like that, especially a punk rock porcupine, it might be a little overwhelming for her.

"This may be the only movie I've ever made that she can see though."

The news comes after the 'Lucy' actress recently admitted she shares the same "dream" as her daughter, as the pair would both love to be Disney princesses.

She said: "My daughter is still young. Right now I think we both share the dream that I will someday be a Disney princess, but it's probably not going to happen. I've been asking for that job for the past 20 years, and nobody has booked me."

Meanwhile, the Hollywood star might not have any films she can show to her young daughter, as she likes to star in films that offer her a "risk".

She said: "I look for projects with filmmakers who want to make things that give the audience a fresh experience.

"I've always been very competitive, and a part of that is pushing your boundaries - taking a risk, and being able to live with the loss that comes with taking a risk."
