Some reports put the figure at Rs.1.2 billion, saying that besides buying the world rights Eros has also bought the music and satellite rights of "Kites".
But neither Filmkraft, Roshan's production banner, nor Eros have confirmed the reports.
"It is just a speculation in the market," a Filmkraft source told Saturday.
The movie, starring Hrithik Roshan and the US-based Spanish model Barbara Mori, is scheduled to start next month. To be shot mostly in New Mexico, Las Vegas and Los Angeles, it will be directed by Anurag Basu with music by Rajesh Roshan.
The movie is about the romantic engagements between an Indian boy and a Latino girl who do not speak each other's language.
