“Willa was nothing short of professional and excellent, and always delivered tremendous performances,” said Amell.

“But I know that she wanted to move on with her career. And I totally respect that,” he continued. “And I’m glad that she’s going to get that opportunity.”

The news may have come as a shock to some fans, but the “Arrow” team was well aware of Holland’s ambitions outside of the show.
