New Delhi, Jan 04 (ANI): Robert De Niro has confessed that his days as a leading actor are long gone, and admits that he is fine with playing supporting roles. The 70-year-old actor told Britain's Metro newspaper that it's life, he can't play certain part anymore and instead is playing the role of the father or the grandfather or the great-grandfather and that can be written in a funny way. The 'GoodFellas' star claimed that now he can't carry the movie as a romantic lead as those days are gone.
