When upcoming actor rejected Salman’s film

We all know what kind of chemistry did Nawazuddin Siddique and Salman Khan created during the filming of their two films Bajrangi Bhaijaan and Kick which became super duper hits in Hindi. 
Now, once they could have been a part of Tube Light but news is that Nawaz clearly rejected the film. Sources say that Nawaz turned down the offer as he was shooting for Nandita Das’s Manto during the Austrian schedule of Tiger Zinda Hai. 
The makers could not shift the schedule and so, they signed a new face instead of Nawaz.
