I am a pessimist by nature says Amitabh Bachchan

The 67-year-old actor better known as the Big B, will be seen playing a flamboyant genie 'Genius', in his upcoming film Aladin and said that the negativity sets in before each release.

"I am a huge pessimist. Every time I do a film I feel like it is going to be a big flop," Bachchan told reporters during a press conference to promote the Eros production which also stars Sanjay Dutt, Riteish Deshmukh and newcomer Jacqueline Fernandes.

The megastar also confessed that he gave a hard time to his director Sujoy Ghosh, but finally stopped meddling when he saw the first two reels of the film.

"I was constantly yelling at him, telling him 'You have not got this right, you have not got that right'... And two days ago I pressurised him to show me something of the film and he showed me two reels and that forced me to zip up," said the actor adding that it was Sujoy who put the 'joy' into the movie.
