Achchamundu! Achchamundu!

Senthil Kumar (Prasanna) and Malini (Sneha) are a happily married couple in New Jersey, living life like any other India-born immigrant couple in the USA. Senthil submerges himself in the office and eats sambar rice at home, and Malini never misses a bhajan at the temple and shops at Indian grocery stores. They have a 10-year-old daughter Rithika (Akshaya Dinesh), the apple of their eye (their car's license plate carries the name of their daughter).

The family has just settled in a new, spacious home about which Malini, understandably, has fears. The couple squabbles amicably about everything from Malini's perpetual laundry and cooking; while Senthil argues with friends about the significance of viboothi and takes his family on weekend trips and birthday parties. It is a normal, happy life in the US until Theodore Robertson (John Shea) arrives, to paint the basement. Now, things are never the same at home again.

Robertson's unusually kind behavior towards children sets off warning bells, especially when he is shown to be a pedophile who exercises like mad within the confines of his home, always moving on towards his next target. How the couple saves their child forms the rest of the story.

Balachander.^[4] The film was shot in New Jersey and New York with a cabin shoot happening near West Milford on 30 May 2008.^[1][3] Dheepa Ramanujam worked as an assistant director.^[5]

The film talks about various issues including pedophilia, the dynamics between a married couple, the lives of Indian Americans, and how "men are from Mars, women are from Venus".^[6]

The soundtrack was composed by Karthik Raja.^[7]

The film was officially selected for screening at the 12th Shanghai International Film Festival (under the International Panorama category),^[8] the Digital Cinema Film Festival in Japan and the Cairo International Film Festival.^[9]

Rediff wrote "For the guts in coming up with a unique, important theme that needs to be addressed sensitively, this movie works. A must-watch".^[10] The Times of India wrote "The average Indian may shy away from paedophilia, but director Vaidyanathan makes a compelling case to watch this film. Subtlety is the byword here rather than gory, knife-edge moments. The approach makes a deeper impression than a dramatic one could have."^[11] A critic from Deccan Herald opined that "Despite its shortcomings, ‘Achamundu Achamundu’ deserves a dekko (watch)".^[12] Gauthaman Bhaskaran of The Seoul Times wrote, "Though “Achamundu, Achamundu” shows considerable restraint when it deals with paedophilia and murder, keeping the actual acts off screen, the film ends up compromising on the dramatic element. It remains pretty flat till about the last 15 minutes out of the total 90 minutes or so".^[1]
