Stewart discusses her career and her new role in On the Road, based on the book by Jack Kerouac, in this interview for PBS. On her character:
Some people aren’t comfortable with being comfortable. Some people really want to be pushed and find people that they can pull something out of you that you didn’t know you had, and you can scare yourself. I sort of realized at that point it was like I need to find people like that – people that are sort of comfortable – people that revel in sort of going a little crazy and following certain lines that aren’t necessarily expected or conventional.
