Ive noticed youve recently had a lot of work that involves a large female ensemble.
Youve said before that you like to make interactive diaries for your characters.
Are those something you share with your castmates?
I dont really show my cast members [the books], which is interesting.
Were so good at keeping it light off set and having fun.
What are some ways you all bond and establish your characters?Its definitely dependent on the project.
Were about to film, and we tried it once, and were like, This doesnt feel right.
What initially excited you about Cassies backstory?
But for her, not being alone makes her feel safe because everyone always leaves.
Do you think her friends take her for granted?
I definitely think Maddy and Kat are closer even though theyre fighting right now.
Shes awesome to work with.
Cassie has found herself in such a range of different situations that feel new to television.
Are there any scenes that have stuck out to you?
Weve got the carousel going on.
We got the crazy frat scene that happened, the pilot itself.
Shes kind of like this extra voice that will speak up if we dont feel comfortable speaking up.
And just having that amazing communication with her is awesome.
Everybody on set, though, it feels like a very safe environment.
Ive never felt uncomfortable or weirded out.
Was part of the appeal in working onEuphoriatackling these kinds of sociopolitical issues?One hundred percent.
TheEuphoriaseason 1 finale airs Sunday at 10 p.m.
