Despite top boiling in the credits , Akshay does not enter the scene till the first hour is comple

Aishwarya Rai Bachchan and Katrina Kaif were the original choices for the roles of Avni and Radha respectively.

Director Priyadarshan worked as the second-unit director of the original movie The Ornate Lock (1993), when he decided to remake the story in Hindi. Akshay Kumar was his first choice to play the male lead role, as was classical dance-trained Malayalam actor Vineet for the role of Shashidhar.

When Avni is brought outside the Palace by one of the co-actor in unstable state we can see the changing of the position of the co-actor scene by scene.

Aditya asks one of the characters to come with him to Malikapur, which another character says its exactly in the center of the country. But when shown the song sequence, they are traveling in a bus which registration starts with KA, which is the registration of Karnataka and the board on the top of the bus is written in Kannada, which emphasizes that the song has been shot entirely in Karnataka which is down south and not in the middle of the country.

During the scene when Aditya (Akshay Kumar) is talking to Shri Yagyaprakashji Bharti (Vikram Gokhale) in the courtyard, we can see a crew member dressed in a black tee and jeans in the background. He makes his way out of the frame, cautiously, so as to not be seen, but obviously fails to do so.

Shri Yagyaprakashji Bharti: [pointing at Aditya] I've seen him somewhere before.

Dr. Aditya 'Adi' Shrivastav: The one who said she was upstairs, but she really wasn't, that's our patient, right?
