"EPI 003 - A SWEET SURPRISE FOR SURIYA SIR! ❤️

The last day of the Andaman schedule was packed with work and a secret plan. While one part of the team focused on wrapping up the shoot, Karthik Subbaraj and DOP Shreyas had something special in mind—a surprise shot for Suriya sir’s birthday special video! But keeping it under wraps was the real challenge.

With the direction team running around, one person whispered, “How do we keep this from sir?” Another sighed, “Suriya sir is too sharp, he’ll figure it out!” Someone even went the extra mile to distract his assistant, just in case. 😄

Amidst all this, Karthik had a wild idea—why not set up a grand entry shot for Suriya sir? Shreyas took it as a challenge and planned an intense focus shift. He zoomed in to the maximum, fixed a point where everything blurred out for a moment, and then snapped into sharp focus—making Suriya sir’s entry look even more powerful. Just when they thought they had it under control, Suriya sir started sensing something was off. “KS always sticks to the script… why this extra shot now?” he asked, suspicious.

Without missing a beat, Karthik casually replied, “It’s a new addition, sir. You’ll love it!” And just like that, the scene unfolded—blood stains, a gun handover, a devilish smile, and BANG! Suriya sir was thrilled. ❤️🔥

The surprise shot and the madness—it all came together perfectly for THE ONE. Karthik pulled it off so smoothly, without giving anything away, and the team’s efforts paid off in the best way possible. A fitting end to an unforgettable schedule!"
