Apu didn't do a screen test but has done a costume trial. "He will shoot for Knockout from the first week of November. Apu has even asked for the dialogues of the film so he can rehearse them. Currently we are doing a high -voltage action sequence with Sanju and Irrfan in Pune. Once that gets done, Apu will begin shooting for the film." Apoorva Lakhia says, "It's rubbish! I am not acting in Knockout! They are all trying to pull a fast one on me but I'm not interested in acting. Dharam, Sohail and the rest are all trying to make a fool of me by spreading such rumours!"
Sanjay Dutt's business manager Dharam Oberoi, adds, "Apu's definitely acting in the film. In fact, he's getting paid 11 lakh for 11 days of work and has already got a signing amount of 2.51 lakh. He's playing a cop who dies in the end as he's shot at by Sanjay Dutt. Apu's theory is that 'if Farhan Akhtar can become an actor after starting off as a director, why can't I?' The producer Sohail Maklai has even given Apu a spot boy while on the sets."
