"EP: 008 - Actor Jayaram and Joju George’s Ragalaigal on sets – The Powerhouse Performers! 💥

Whenever Karthik Subbaraj delivers a dialogue or hands over the lines to Jayaram sir, he often mimics other actors’ voices, making everyone on set burst into laughter. 😆😂 Sometimes, even during takes, he creates such a fun atmosphere that the entire crew struggles to hold back their laughter—leading to multiple retakes. 🎬 However, despite the chaos, he always manages to execute his work flawlessly while others are left giggling. 😎

Jayaram sir frequently imitates Thalaivar’s voice as our Pandiyaa is a big fan of Thalaivar!

“Betty bought some butter, and the butter was bitterrerrrr!" 🤘🏻🗿 – a classic example of his playful antics on set!Even Suriya Sir became a "victim" of Jayaram’s witty jokes and counters. 😂 While Jayaram sir performed his dialogues with precision, he often made Suriya sir laugh uncontrollably during takes, making the shoot even more lively. 😀

Then comes Joju George, whose Tamil skills have been honed by none other than Karthik Subbaraj, his unofficial Tamil teacher! 👨🏻‍🏫 During rehearsals, Joju George sir would sometimes translate lines from Malayalam to Tamil, testing different pronunciations. However, when the cameras rolled, he delivered his Tamil dialogues with perfect fluency, leaving everyone impressed by his flawless Tamil pronunciation and natural dialogue delivery. 👌🏻🤌🏻

Directing these two powerhouse performers was an absolute delight—filled with laughter, spontaneity, and fun. 🤩 Yet, when it came to work, their professionalism and dedication were second to none. 👍🏻🔥"

Starring and co-produced by Suriya, Retro is written, directed, and jointly produced by Karthik Subbaraj. The movie releases in theaters on May 1, 2025.
