Telugu actor Ram Charan Teja was apprehensive to star in the remake of ‘Zanjeer’ but says it was his superstar father Chiranjeevi, who came to his rescue and made him sign the film. ‘Zanjeer’ is the remake of the hit 1973 Amitabh Bachchan starrer. The film marks the Bollywood debut of the 28-year-old actor, who admits that the thought of reprising the megastar's iconic character Vijay was unnerving at first.
