It was reported this week that the Agent Vinod actor was taking on a superhero role for the first time.
Luthria told the Hindustan Times: "No, it's not a superhero film. Saif is not playing a superhero in my film. People have misinterpreted me and come to the conclusion. The film has all the elements of fantasy. When you have a very good script, it becomes difficult to put it into a particular slot or genre.
"Saif will be seen playing a role that he has never tried before. I have a fantasy element in my film and that's my trump card. In many ways, I can say that it's a very Manmohan Desai kind of a film. Saif has been proving himself in new ways, be it Dil Chahta Hai, Race, Love Aaj Kal, Ek Hasina Thi or anything else. He has proved his versatility.
"There is a lot of excitement with this film. When we first worked together, that time he was a little raw and I was new. Now we are meeting when we both are at the top."
In March, Khan admitted that he had wanted to be a cricketer like his late father before getting his first lead role in Hum Tum.
