Priyadarshan likes to work without a script, while Anil does projects only when he is given a hard-bound script.
"To put it bluntly, Priyan and Anil do not see eye to eye. Anil is a studied actor who likes to come fully prepared to the sets. For this, he needs the script beforehand. Priyan, on the other hand, seldom, if ever, prepares a full script. Most of the time he likes to improvise and work out his scenes on the spot. This is not how Anil likes to work. He turned down every single offer from Priyan until 'Tezz'," said a close friend of Anil.
For "Tezz" apparently, Priyadarshan had no choice but to write out a full screenplay before shooting.
"Priyan needed to shoot in various parts of England, including Glasgow on subway and railway stations where permission had to be taken from various authorities. Priyan needed to submit a screenplay to the British authorities for each location that he needed to shoot on. That's how Anil was given a script this time by Priyan," said a source.
Priyan constantly improvised and altered scenes at the last minute, thereby throwing the pre-prepared Anil Kapoor off guard. Reportedly there were constant arguments between the actor and director caused by their antithentical modes of working.
Consequently, Anil is unlikely to return to Priyadarshan's cinema after "Tezz".
