The film also stars famed action star Jean Reno. She speaks about working with the legend, saying:

"Jean Reno plays the bad guy, brilliantly at that. He's such a talented and incredible human being, and just this incredible force to be around and to work alongside. He's so much fun to be around, he's nothing like any of these scarier characters he's played. He's actually really very warm, funny, and charming. I really adore him!"

Rose began filming The Doorman after suffering an injury on the Batwoman set eventually leading to her departure from that role, which will now be played by Javicia Leslie. Luckily, Rose was still able to perform stunts for the film. She spoke about the ease of performing stunts thanks to director Ryuhei Kitamura, saying:

"Ryuhei is incredible with the action scenes and so were our stunt coordinators," she explains. "I can easily say our action scenes in the film are on another level. We had so much fun shooting them, especially in all the different locations we got to play in. There's a mixture of martial arts, weapon training, and a lot of physical hand-to-hand combat."
