A day before release, Shah Rukh Khan's Pathaan leaked online

Pathaan, starring Shah Rukh Khan, Deepika Padukone and John Abraham, is scheduled to release in over 100 countries on Wednesday. 

The film, which marks a comeback for Khan, is set for a bumper opening with record advance bookings, selling over 5 lakh tickets on its first day.

However, the film is already available on two websites called Filmyzilla and Filmy4wap, Times Now reported.

One website describes its version as a "camrip" and the other as a "pre-DVD rip."

Pathaan producers Yash Raj Films have urged fans to watch the film in cinemas and have cautioned against leaking footage recorded from the big screen.

"All set for the biggest action spectacle? A humble request to everyone to refrain from recording any videos, sharing them online and giving out any spoilers. Experience Pathaan only in cinemas," YRF tweeted with an email address to which piracy can be reported.

Pathaan has already made a box office record even before release. Its ticket sales for Day 1 – over 5 lakh – are second only to those of Baahubali: The Conclusion.
