Los Angeles: Steven Spielberg`s obsession with dinosaurs is not over yet.
The Hollywood veteran is reportedly brainstorming with writer Mark Protosevich to reboot the lucrative franchise for a fourth movie.
The director is already set to launch the television series Terra Nova on Fox besides working on the ideas for a possible revival of dinosaurs on the big screen, the Hollywood Reporter said.
Several years ago, the Oscar-winning director worked with Protosevich on a potential remake of Chan-wook Park`s Oldboy that was to star Will Smith.
That film ran into rights problems and didn`t come to fruition, but Spielberg, who directed the first two Jurassic Park films and was an executive producer on the third, has since met twice with Protosevich to fashion a story for a potential fourth film in the franchise.
The franchise, born of the late Michael Crichton`s 1990 novel, has been in cold storage since 2001, when Joe Johnston directed `Jurassic Park III` from a script by Peter Buchman, Jim Taylor and Alexander Payne.
The third film grossed just USD 369 million worldwide while `Jurassic Park` and `The Lost World: Jurassic Park` grossed USD 915 million and USD 619 million, respectively.
