Shah Rukh Khan is all set to dial up the action quotient once again, and this time, it's on a scale that promises to be nothing short of spectacular. The actor will soon be filming a massive, high-intensity action sequence for his upcoming film King, directed by Siddharth Anand. What makes this particular sequence stand out is the involvement of 10 trained Russian fighters, who have reportedly been brought in to execute one of the film's most crucial action blocks.
