'I feel like I accomplished something': Hailee Steinfeld on TIFF 2016 closer The Edge of Seventeen

As she prepared for Saturday's world premiere of The Edge of Seventeenat the Toronto International Film Festival, teen superstar Hailee Steinfeld said she felt like it was a defining moment in her career.

"I feel like I accomplished something," the Oscar-nominated actor-singer said in an interview before the screening, which served as the festival's closing night film.

"I feel like I met a truth that I haven't maybe in other movies or necessarily with a character like this."

Steinfeld, 19, is getting early rave reviews for starring as heroine Nadine, a socially awkward, self-absorbed teen who revolts when her best and only friend (played by Haley Lu Richardson) starts dating her brother (played by Blake Jenner).

Woody Harrelson plays Nadine's history teacher, who tempers her melodrama when she confides in him, while Kyra Sedgwick plays her widowed mother.

Charming the critics

Kelly Fremon Craig wrote and made her feature directorial debut on the coming-of-age story, which is charming critics: Variety describes it as "the savviest teen comedy in years," Indiewire says it "resurrects the teen comedy" and the Hollywood Reporter calls it "really, really good."

Steinfeld, who got a best-actress Oscar nomination for playing a farm girl in True Grit,said she was able to help shape Nadine and inject her with a vulnerability she's never tapped into before.

"I've worked with coaches before who've told me before going into an audition I'm like shaking because I'm so nervous and they're like, 'Use it,'"said the Pitch Perfect 2cast member, who will also be in the third instalment.

"I never knew what the meant until I played this part, being able to use everything within me. And there were so many things dealing with the movie and my personal life and phone calls and this and that and emails and whatever.

"Going to set every day and just putting it all behind me but laying it all out was what I felt I could do."
