Bollywood actor Anil Kapoor thinks his daughter Sonam Kapoor still needs to "improve" a lot.

"One might be best actor or actress in the world but he/she has to keep on learning, same goes for Sonam. No matter how much praise she gets for her performance and whatever anyone says, she still has to improve more and more," Anil Kapoor said at the red carpet of Zee Cine Awards.

"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," the "Welcome Back" actor added.

On Sonam's latest flick "Neerja", dad Kapoor said: "... there is a kind of emotional reaction in the entire family. We feel that this film somewhere is blessed by Neeja herself. Whatever good is happening with the film is all because of her." 

Neerja is based on the life of air hostess Neerja Bhanot who was shot dead by terrorists. 

The movie revolves around the actual hijacking of Pan Am Flight 73 in Karachi, Pakistan on September 5, 1986.
