Sienna Miller wish to retell her previous movie from her characters' perspectives

Actor Sienna Miller says her upcoming film "American Woman" felt like a breath of fresh air to her as she got tired of being boxed into a certain image.

Miller, who had a breakout role in "Factory Girl", feels she got relegated to smaller and supporting parts with the films "American Sniper", "Foxcatcher", "The Lost City of Z" and "Burnt".

"In many cases, I still fantasize about going and retelling the entire movie from my character's perspective," the actor told The Hollywood Reporter.

She said "American Woman" is the one film "she is most proud of". The movie is about a woman who goes through several stages of her life and the tragic events that shape her.

"It's the kind of film that is being made today, I think, because of a shift in our industry to focus on telling female stories," Miller said.

"I wonder whether people would have been interested in looking at that kind of story. (And) studios are being much more cautious in how they value women, how they treat women," she added.

Directed by Jake Scott, "American Woman" had its world premiere at the ongoing Toronto International Film Festival. The film also features Aaron Paul and Christina Hendricks in pivotal roles.
