"Let me correct you, we are not playing real life characters," said actor Akshay, who plays Shoaib Khan in the underworld drama, in which Imran Khan will be seen as Aslam.
"I am playing Shoaib's character and he is playing his character, there is nothing called real life character", added the star at a media meet, when asked whether the duo have done any research on their respective characters.
"It's a fictional film. Lot of small, small incidents have been taken and added here," he said.
Imran added: "It is a fictional story and as Akshay said incidents are picked up, modified and used here."
Directed by Milan Luthria, Once Upon a Time in Mumbaai Again also stars Sonali Bendre and Sonakshi Sinha. Produced by Ekta Kapoor and Shobha Kapoor, the film is slated for August 8 release.
