For his next film, 'Dangal', Aamir Khan has been working on his Haryanvi accent with help of diction trainer Prakash Bhardwaj. Having struck a rapport, the latter has secured the star's involvement in his recently-announced project, 'Gulam Bandhu', which is slated to go on floors next year.

Says Prakash, "I met Aamir and narrated the script to him. He suggested a few changes, which I have already incorporated. Once the casting and pre-production work is done, I will request Aamir to support my film in any which way."
