Actor Sidharth Malhotra says hand-to-hand combat techniques have been used for the action sequences in his forthcoming film "A Gentleman: Sundar Susheel Risky", and they are all doable.Sidharth, who will be seen as Risky Rishi, uses the hand-to-hand combat technique in the film, which also stars actress Jacqueline Fernandez.The actor was trained for the action sequences by the Hollywood action choreographer Cyril Raffaelli, known for his work in films like "Tekken" and "The Transporter".Sidharth said in a statement: "It's purely hand-to-hand combat. We had an action choreographer from Paris. Cyril Raffaelli has done loads of Hollywood films and he was training me. So, whatever action you see is all doable, it's all hand-to-hand technique."Giving more insight into the action choreographer, director Raj Nidhimoru said: "Cyril is one of the first guys who started Parkour, and is very good at hand techniques." "Sid trained for quite a few weeks, and he's got some really good moves now. So nobody can mess with him," he added.Produced by Fox Star Studios, the film is directed by Raj & D.K. It is set to release on August 25.
