 The film is a takeoff on the Ramayana, as the names show: Ram, Lucky  (Lakshman) and Raghavan (Ravana). Also, as a reference, in the  movie, Lucky (Lakshman, played by Zayed Khan (qv)) mentions that  the house would feel like a Mahabarat if he kept his name as  Lakshman. Then his brother and mother correct him by saying Ramayan.
