As Sri Ganesh's 3BHK, starring Sarathkumar, Siddharth, Devyani and Meetha Raghunath, and director Ram's Paranthu Po, with Shiva, Grace Antony and Mitul, releasing on the same date (July 4), those involved with both films have been cross-promoting their films.
Siddharth recently attended the audio launch of Paranthu Po. Ram was at the 3BHK pre-release event, praising Siddharth and wishing his film a big success.
Ram said he is similar to Siddharth, both are innocent and cannot design their speech and thoughts to suit a particular occasion. He shared that he has had a close bond with Siddharth since Kattradhu Thamizh. Ram said, "Since Kattradhu Thamizh was off-beat, not many liked to be in my contact. But Siddharth, who was fresh off the blockbuster Bommarillu, liked the film, and we kept in touch since then."
The trailer of 3BHK suggested that the family is trying its best to build a house. The film is produced by Arun Viswa of the Shanthi Talkies banner.
