Welcoming the Malayalam megastar on board, the production house wrote, “When the Big M chooses a story, it becomes history. Super excited to welcome Megastar @mammukka onboard #D55!” The images quickly went viral, marking the beginning of what many are calling one of the most exciting cross-industry collaborations in recent years.
