Asked if there's anything he would like to ask himself at this stage of life, he said: "Why have I been such an idiot?"
"I have asked this question to myself because understanding and time is a part of very few lucky lives. When one has time, then the understanding is not there, and when you have the understanding then you don't have the time," he added.
Annu, who will soon be seen in Rumi Jaffery's "Gali Gali Chor Hai", admits he lives with some regrets.
"I honestly feel that there are a lot of things that I could have done, a lot of opportunity that I could have grabbed and a lot of moments I could have lived better. Now when I have understanding of things, I don't have much time. I know I am no more a young man," he said.
However, the 55-year-old says he tries to do different things by essaying all his movie characters with a fresh approach.
"I never go back to my characters that I have played earlier. I always like to have a fresh approach to the characters I play. I go from character to character and from film to film," said Annu.
Last seen in "7 Khoon Maaf", the actor returns as a corrupt cop in "Gali Gali Chor Hai". He will also be seen shaking a leg with Pakistani actress Veena Malik in an item song.
"I represent the system, a part of the system that gets most of the limelight and that's corrupt cops," he said of his role.
