Ranbir Kapoor said he is "very excited" to collaborate again with his debut film 'Saawariya' director Sanjay Leela Bhansali in 'Love & War'. "He is my godfather. Everything I know about films, everything I know about acting, it's something I learnt from him," he added. "He hasn't changed at all. He is extremely hard-working," said Ranbir.
