When Gautam goes to impress dadi, before ringing the bell he puts on his shades but in the next scene when dadi attacks on him, his shades are missing.
In the beginning of the film, Marru was imagining his uncle as his servant, where Marru arrives in a Mercedes car and his uncle wipes the widow of the car. At the end of the film, when Tanushree Dutta was leaving, they used the exactly same Mercedes car. In those two scenes the plots were totally different, but the car was the same.
Same locations are used in several scenes.
