The Dabangg 2 helmer is making his directorial debut with the action thriller starring the veteran actor.
He told The Times of India: "He is a brilliant and spontaneous actor. He knows the camera and knows his audience. This comes after many years of experience.
"He is so much at ease with himself. There is a comfort and freedom in his performance. He is incorrectly perceived to be indisciplined. He is not an early morning person so, unless he has to, he will resist coming to shoot at 6 in the morning.
"So if a director cannot work around his timings, he should not work with him. Once you suit your time cycle with him, he is not indisciplined. If he knows there is a sunrise shoot which has to take place at 7am, he will even stay back in the make-up van at night for the shoot."
Arbaaz added: "The kind of space and popularity Salman is in right now, anyone [else] will have difficulty getting any recognition in his film. He is a great star, but it's not that you can just roll the camera on him.
"He will come on the set with his expertise as an actor and great stardom, but you can't make him act in a void."
In July, Arbaaz admitted that filmmakers and actors from famous families are more likely to be successful in Bollywood.
He took on the directorial role for the sequel after Salman Khan decided to sack the entire production crew for the original film.
