Kristen Stewart has confessed that she often worries about "little things" she's done wrong in past acting roles.
The Welcome To The Rileys star told MTV News that shooting the film allowed her to delve deeper and bring more to the part than in her past movies.
"I could sit here and bring up little things that I wish I didn't [do], little things that kill me, stuff that maybe other people don't see but stuff that is very apparent to me," she said.
"It was so everything that it should be. If I did bring my little things to it, we did share a few personality aspects. I think that's maybe why I was hired. It was a stretch, because obviously I live nothing like she lives."
She added: "It's always really hard to say why you've progressed as an actor. I feel like I've gotten better with every movie."
Welcome To The Rileys opens in limited release in the US on October 29.
