"This is a huge topic, especially right now with what's going on in the world," she added. "And it's so close to home and it's so important to portray it properly. I felt a huge responsibility to make it real, but then also there was a part of me where my heart was breaking. So it was a very interesting moment for me to get that [script] and there was no warning coming."
