Bollywood actor Anil Kapoor says daughter Sonam will have to keep improving her craft, in spite of establishing herself as a fine actress with her latest, "Neerja."
The Slumdog Millionaire star said "An actor is always a student. Acting is a vast learning like an ocean. You can never absorb it completely. An actor always needs to keep learning, and make an effort to do better every time."
Neerja is based on the life of air hostess Neerja Bhanot who was shot dead by terrorists. The film revolves around the actual hijacking of Pan Am Flight 73 in Karachi, Pakistan on Sept 5, 1986.
