The 43-year-old Singham star, who is married to actress Kajol and has two kids Nysa, 9, and Yug, 3, says he becomes the character he is playing in front of the camera.
"I am a very spontaneous actor. I feel the character. I am the only actor in the industry now who is doing every genre and audience have accepted me with open arms. I try to be the character. Instead of the character becoming Ajay Devgn, Ajay becomes the character," the actor told PTI.
"An actor job is just to perform. It's not physically and mentally tasking. Some people are method actor and I am not that kind. I feel the character in front of camera and I just behave like that," he said.
Ajay started his career as an action hero with hits like Phool Aur Kaante and Vijaypath. He went on to win the National award twice for his performances in Zakhm and The Legend of Bhagat Singh. He also proved his mettle in comedy with Rohit Shetty's Golmaal series.
Ajay was recently seen in Sajid Khan's Himmatwala, where he reprised the heroism of 80s era.
"The film is based in 1983. Hero has always been a hero in our country. The thought has been picked up and I won't call it a remake. The film is completely different. Sajid just kept the base same. There the character was an engineer and here he is a street fighter," the actor said.
Ajay is currently shooting for Prakash Jha's Satyagraha in Bhopal with megastar Amitabh Bachchan.
Asked about his experience of working with Bachchan, Ajay said, "I must have done 7-8 films with him. He is like a family to me. I respect him and adore him. He is a brilliant actor."
They have starred together Major Saab, Aag, Khakhi, Hum Kisise Kum Nahin and Hindustan Ki Kasam.
