A countdown currently running on the movie's official website is scheduled to end at 9pm on Thanksgiving night (November 27), leading many fans to speculate that its culmination could be the unveiling of a trailer, reported Ace Showbiz.
Universal Studios has also launched a separate viral site based around the Masrani Global Corporation, a company founded in the upcoming movie by magnate Simon Masrani, played by Indian actor Irrfan Khan.
The Masrani viral site includes details on events that occurred after 'Jurassic Park III', including Simon purchasing the InGen theme park from the late John Hammond (Richard Attenborough) and opening the dinosaur attraction in 2005.
Included on the site is the first image of Irrfan Khan as Masrani, and a shot of BD Wong reprising his franchise role as Dr Henry Wu.
