In addition to its fourth season renewal, there has been plenty of casting news coming out of DC’s Legends of Tomorrow. The most recent being Jes Macallan who has been promoted to series regular in the superhero series.

Macallan joined the CW series at the beginning of season 3 as Time Bureau agent Ava Sharpe. Her character was also promoted to the head of the agency. Her character was a love interest for Sara (Caity Lotz) and was later revealed to be a clone.

“Jes has a power to captivate in person as well as on screen. She had been guest-starring on Legends for all of two days when one of our teamsters, the guy who had been driving her to set, told me that we ought to make her a series regular. He wasn’t wrong,” executive producer Phil Klemmer said in regards to Macallan’s promotion. “We knew that we wanted Sara to fall in love with someone in season 3, and our challenge was to come up with a character worthy of our fearless captain’s love — and then the second challenge was to find a performer capable of playing that part. The door had barely closed on Jes, having just finished her chemistry read with Caity Lotz, that we all turned to each other and agreed that we had found our Ava.”

Klemmer adds: “Her character arc was a bit of a slow burn this season, and yet each episode revealed a new facet of her character. She’s been alternately funny, poignant, engaging, endearing, and kick-ass this season — and yet I know for a fact that we haven’t hit all of Jes’s hidden gears as an actor. We are lucky to have a whole new season in which to find them. It’s not every actor who can find the emotional heart of a storyline that features John Constantine, a chicken, and a severed human foot. Thank God we found Jes Macallan.”

Macallan is also known for her role as Joss on ABC’s drama Mistresses. She is repped by Elevate Entertainment, Innovative and Ginsburg Daniels.

The season finale of Legends of Tomorrow will air at 8 PM ET on Monday April 9.
