Everyone knows that the otherwise workaholic Akshay Kumar shoots only six days a week keeping Sunday for his family. But not any long! Breaking away from his self set norms, Kumar has broken the rule for Balaji and Milan Luthria's forthcoming film Once Upon A Time In Mumbaai...Again (OUATIMA). The last time he worked on a Sunday was when he was shooting for Priyadarshan’s Bhagam Bhag way back in 2006. Remarks a source, “Milan (Luthria) has been down with viral. Therefore the shoot had to be cancelled for three days. So Akshay agreed to work on 7 April (Sunday) to make up for the lost time.” That day, Akshay worked with his co-stars Imran Khan and Sonakshi Sinha from 7 am till late that night. Incidentally, Akshay is expected to be working next Sunday as well. The superstar, who has been dubbing for OUATIMA simultaneously, is mighty pleased with how the film has been shaping up. OUATIMA is set for an Eid release.
