Emma Corrin got candid about what she did to get in the character of Charles Xavier aka Professor X’s evil sister Cassandra Nova in the new Marvel crossover Deadpool & Wolverine, which hits theatres on July 26th.

“I did look back at those two performances,” they told Screen Rant. talking about the role of Dr. Charles Xavier, previously played by Patrick Stewart and James McAvoy.

“I hesitated before I did because I was like, ‘Do I want to get too close? Will I still be able to make it my own?’”

“But I found it really interesting how they portrayed someone whose power is very internal and telepathic in that telepathic world. I wanted to see if there were any bits that I could use or pay homage to that, obviously, fans would really enjoy.”

“But in terms of the comics, we very much stay true to the comics in terms of Cassandra’s look, the cap and the costume and the weirdy fingers, and definitely, you’ll see echoes of her origin story and her relationship of her brother are very prominent here in terms of her motivation,” Corrin said.
