India, March 22 -- Actor Shah Rukh Khan is gearing up to shoot for a high-octane action sequence for his upcoming action thriller, King. Helmed by Siddharth Anand, the film is scheduled for a theatrical release in December this year. What makes this scene stand out is the involvement of 10 trained Russian fighters, who have reportedly been brought in to execute one of the project's most crucial action blocks. According to Mid Day, the scene will be shot inside a studio in Vile Parle, Mumbai, where an elaborate set resembling an old, abandoned mill has been specially constructed. The shoot is expected to commence around March 23 and will continue over the course of a week, with the actor leading the action-heavy scenes."It's one of the most elaborate action stretches planned for the film. The stunts designed are gritty and realistic, and the stunt artistes have been prepping for the past few weeks," said the source, adding: "It's designed as a big moment in the film, visually striking and mounted on a scale that complements the larger-than-life tone of 'King'."
