Tall and brawny actor Sonu Sood has done many stunts in his career. But he says in Rohit Shetty's Simmba, he has done something "special".

Sonu, who paid a tribute to Bollywood's action heroes at the opening ceremony of the 49th International Film Festival of India (IFFI) here, believes times have changed for action sequences in the Hindi film world, and Simmba will be an example of how it has evolved.
