"A lot of stars have been mimicked in the film. Dabbooji (Randhir) is Sajid Khan's favourite topic of imitation," the 43-year-old said here Wednesday on the sets of "Dance India Dance Li'l Masters."
"It is said that imitation is the highest form of flattery and since I respect my father-in-law a lot, we decided to honour him in the highest way," he added.
The cast of "Humshakals", barring Bipasha Basu, and director Sajid, was present here to promote the film.
"Humshakals" also stars Riteish Deshmukh, Ram Kapoor, Tamannaah Bhatia and Esha Gupta. The film hits theatres June 20.
