Stepping in the shoes of junior Aamir Khan in the recent mega hit ' Dhoom 3 ' was not a cakewalk. The 13-year old Siddharth Nigam stole the show as the little wonder of this pacy-thriller. Siddharth did impeccable magic tricks, awesome gymnasts in the film and made everyone speechless with his excellence.

Siddharth is a national-level gymnast from Allahabad and all the jumps and flips in the films are done by him, said the director Vijay Krishna Acharya . The kid was with the director for three months and he attended the workshop organized by the director for him. The kid has the high-degree chances to feature in Dhoom franchise after growing up, as told by the director. Acharya spotted Siddharth in Bournvita commercial and instantly, locked him as the junior Aamir in his film.

The wonder boy Siddharth revealed his experience of featuring in the film by saying that "I had no problem doing any of the scenes. The only time I had a problem was when I had to call Jackie Uncle, 'Papa'. That felt....strange. Otherwise kab shuroo hua kab khatam hua pataa nahin chala. Bahot mazaa aaya,".
