After Quentin Tarantino's script leak fiasco another such case has emerged, although not as serious, where the trailer for the film adaptation of John Green's best-selling novel, The Fault in Our Stars, leaked online.

According to Indystar the video doing the rounds in social media has "all the markings of a legitimate trailer." The video appears to have been recorded while it was playing on a laptop. A series of numbers and letters covers the middle of the screen throughout.

The film has actors Shailene Woodley and Ansel Elgort portray Indianapolis teens Hazel Grace Lancaster and Augustus Waters, two cancer patients who fall in love.

The trailer of the film was expected to release on Valentine's Day (February 14) as per multiple sources including Green, the film's Twitter profile @TheFaultMovie as well as the father of the director, Josh Boone.

"Green fans who wait until Valentine's Day will have a better viewing experience, but the temptation to watch more than 2 minutes of footage may be too great to resist," states the Indystar report.

While Green has so far not commented on the film's trailer leak, he did tweet about the success of the book, on Monday:

The Fault in Our Stars generated a lot of negative publicity in December last year over its official poster tagline, "One Sick Love Story". It was deemed controversial due to the film's heavy focus on cancer.

Sharing her displeasure over the marketing campaign of the film, Woodley told Entertainment Weekly that even she would not have chosen a tagline like that "by any means."

"The Fault in Our Stars" was shot in Pittsburgh and Amsterdam in 2013 and will premiere in US theaters on 6 June.
