By now its common knowledge that Vipul Shah is all set to take a trip down the retro lane with his Akshay Kumar- Aishwarya Rai Bachchan starrer Action Replayy. However, what did catch us by surprise was when we saw this picture of Akshay in a complete retro rock star look from Action Replayy. Apparently, Akki’s look in this particular dance number is modeled on the lines of John Travolta’s in the cult classic Grease. Akshay, who is a huge John Travolta fan, was more than happy to step into this get-up for this special song sequence with Ash. The duo thoroughly enjoyed practicing the dance steps of the disco era for this particular song. An elated Akki, who thoroughly enjoys listening to retro music, said, "The 70s was full of energy, that’s the reason why retro is hip. There is something about the fashion and music of that era which makes it so funky even today and perhaps it will always be that way." With Akshay and Ash bringing together a sizzling chemistry in this electric number, filmmaker Vipul Shah must be surely grinning from ear to ear. After all, it looks like he has a winner on hands.
