The dream collaboration that fans have been waiting for decades has finally materialized. Kamal Haasan and Rajinikanth, two of the biggest stalwarts of Tamil cinema, are set to share the screen once again in an upcoming film, tentatively titled #KHxRK. The announcement was officially confirmed on February 21, 2026, when production house Red Giant Movies dropped a brilliant promo that has since sent social media into a frenzy .

This marks the duo's first full-fledged on-screen reunion in 47 years. They were last seen together in the 1979 fantasy film Alavuddinum Athbutha Vilakkum . The news was first hinted at last year, and Kamal Haasan had confirmed the collaboration in September 2025 at the SIIMA awards, playfully explaining their reunion by saying, "We were united long ago, but chose to remain apart because they kept splitting a biscuit and giving us only half each... Now we are content with just half a biscuit again, so we have come together" .

A Quirky Promo with a Retro Vibe
True to director Nelson Dilipkumar's signature style, the three-minute-46-second promo is filled with light-hearted, quirky banter . The video begins with Nelson standing confused in a hotel corridor, unsure whose room to enter first—Rajinikanth's or Kamal Haasan's. He is then joined by music composer Anirudh Ravichander, who playfully asks Nelson to choose between two classical ragas, "Shanmughapriya or Kokilapriya?" .

The fun continues as Nelson visits the superstars' rooms. In a hilarious sequence, both legends are seen second-guessing their retro-style wardrobe choices—from blazers to shoes—when they learn what the other has selected . Eventually, the two icons emerge from their rooms, twinning in stunning retro avatars, complete with stylish suits and sunglasses, before walking towards a vintage car in a lavish garage .

The promo ends on a playful cliffhanger. As Nelson and Anirudh join the superstars in the car, Kamal turns to the director and asks the million-dollar question: "Who is the hero?" Rajinikanth chimes in, repeating, "Tell us, who is the hero?" leaving Nelson with a perplexed expression as the car zooms away .

Powerhouse Crew Behind the Camera
The yet-untitled film boasts an impressive technical team. It is directed by Nelson Dilipkumar, known for his blockbusters like Doctor and Jailer, who is already collaborating with Rajinikanth on the highly anticipated Jailer 2 . The music will be composed by the rockstar Anirudh Ravichander, promising a soundtrack that the makers describe as a mix of "Beethovan mixed with Bappi Lahiri" .
Adding to the grandeur, acclaimed cinematographer Rajiv Menon (known for Bombay, Kandukondain Kandukondain) will handle the camera, with R. Nirmal as the editor and DRK Kiran as the art director . The film is produced by Inban Udhayanidhi under the Red Giant Movies banner .
