According to the reports Shahrukh Khan has already taken place of Aamir Khan in the upcoming biopic titled as Salute. 

With an interaction with the movie a source had revealed to a daily, "Aamir strongly recommended the Rakesh Sharma biopic to Shah Rukh as a script worth walking that extra mile for. More so, since Aamir intends to devote a substantial period of his time to a very dear project of his, presumably the Mahabharat, and has stopped accepting any other assignments currently." 

Now, as per reports in a leading daily, SRK is leaving no stone unturned in taking Aamir's help for researching the project and prepping well for the same. A source revealed to the daily, "King Khan has asked Aamir to help him out with the research he did for the film when he was supposed to do it. Knowing what a perfectionist Aamir is, he must have done detailed research and SRK will only benefit from that."

 Shahrukh Khan will commence shooting for the movie from September to November, then take a break to promote Zero and get back to work on Salute from January 2019. The film is expected to release next year.
