Even after five and a half decade in cinema, superstar Kamals Haasan says that he still needs training. This Padma Shri and Padma Bhushan awardee was in Hyderabad to promote his upcoming Telugu film 'Chikati Rajyam' - the Tamil version is called 'Thoonga Vanam' - and it is a remake of the French film 'Sleepless Nights' (Nuit Blanche). "Sleepless Nights is a good film. I wanted to remake it as it is a thriller and one feels the depth of the characters in the story, Kamal explains and added that it was adopted to suit Indian sensibilities." Kamal has written the screenplay and his assistant Rajesh M Selva has directed it. Kamal said that training is necessary to hone one's skills. "Now we go to US for sound recording but in a few years, we will not need that. It will be made in India," he says, adding: "I need training as well. There is so much to learn. One needs to learn."
