And then I was flown out to L.A. for two auditions in person, one with Sarah.
So all in all, it was four rounds of auditions, a three month process.
And I got the part, and a few days later I was on a plane to Canada.

Theres so much granular work that goes into every little shot that I had never even thought about.
I would just be like, Im gonna be spontaneous and free, and do the shot!
So things like that were constantly surprising.

And even to read opposite someone like Sarah was so exciting.
And then I had to do the job, which was very, very scary.
By the second week, it was just kind of like, Oh, this is my job now.

And its the coolest job in the world!
What was your relationship with Sarah like on set?Sarah was immediately so warm and welcoming and kind.
She made such an effort to make me feel included, to make me feel confident.
I definitely felt like she had my back all the time.
And so any day I was on set with her, I felt safe.
I know Aneesh was very insistent on having a performer with a disability play this character.
Do you know whats next for you?Well, Im in college right now.
This movie, believe it or not, actually comes out on the first day of my finals week.
So I definitely have a very full life right now, in wonderful, wonderful ways.
I would love to be an actor for the rest of my life.
