7G Rainbow Colony

Production

Selvaraghavan revealed that the inspiration for 7G Rainbow Colony came from his college days when he had been fascinated with a Punjabi girl during his education in KK Nagar. He based several of the scenes on real-life happenings with his friends, revealing that the film was over 70% biographical and the lead character was an "average" person like himself. Ravi Krishna, son of producer A. M. Rathnam, made his acting debut. According to him, Suriya and Madhavan were the initial choices for his role, but could not accept as they were busy with other films. Swathi Reddy was initially cast as the lead actress in 2003; she shot for around 20 days but left to focus on her education. Sonia Agarwal was later cast in her role. The film was simultaneously shot in Tamil and Telugu languages; scenes were shot in Tamil first and then in Telugu. Filming took place mostly in Hyderabad. The Telugu version was initially titled as Naakoka Girl Friend Kaavali.
