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 besides working on the ideas for a possible revival of dinosaurs on the big screen.

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.
