Ritesh Rana, the writer and director who rose to prominence with Mathu Vadhalara, is back with Happy Birthday, a quirky comedy starring Lavanya Tripathi. On July 15, the film, which also stars Naresh Agastya, Rahul Ramakrishna, Vennela Kishore, and Satya, will be released in theatres. Clap Entertainment and Mythri Movie Makers collaborated on the production of Happy Birthday. Over the past few days, the makers of Happy Birthday have released character promos for most of the film's major characters. The cast and crew shared a sneak peek at Lavanya Tripathi in the film earlier today. The actress is introduced as a modern, beautiful girl with the nickname Happy 340 in a short promo. Lavanya embodies arrogance while wielding a rifle and clothed in golden garb.
