The director of the Fame remake and upcoming Mortal Kombat reboot lost out to Gary Ross for the gig, but has revealed that he used the video, which consists of clips from other movies such as Harry Potter, Twilight and Gladiator spliced together, to pitch his vision for the film to executive.
Speaking to SlashFilm, Tancharoen said of the video: "The idea of a 'pitch reel' has been around for awhile and is very common practice for any director. Trying to pitch a vision to a room full of people is always very difficult verbally.
"It's almost expected for a director to show some visual materials, but the need to impress has become elevated. At first, it was just some concept art, some storyboards and possibly a treatment. Then the rip-o-matic [a visual reel using clips from other movies to portray a visual style] became really popular."
Tancharoen said the composition of the trailer took him "about a month" and said that making it helps a great deal to assess the tone of a film as "you have the feeling that this is what the movie will be like when it's done."
He claimed to harbour no ill-feeling about not getting the job, saying: "I really loved the film that Lionsgate, Gary Ross, and Nina Jacobson made - I went opening night."
He then said that he hopes the circulation of the trailer will prove instructive to other filmmakers, adding:"I've always enjoyed when other directors showcase their process... it has helped me learn tremendously."
Gary Ross has since departed the Hunger Games franchise, and has been replaced by Water for Elephants director Francis Lawrence for the next instalment, Catching Fire.
