Director Steven Spielberg is so eager to get the fourth installment of his mega successful dinosaur film Jurassic Park moving, he's considering directing it himself.
The Oscar-winning director did the job himself on the first two films in the franchise before he passed the torch onto fellow film-maker Joe Johnson for the (much) less successful third movie.
According to Sky News, Johnston is still Spielberg's first choice to direct number four, but if he is unavailable Spielberg will step back into the director's chair.
The film is currently slated for release in 2008 and the script is still being finalized. Spielberg is also on track to direct the fourth installment of Indiana Jones.
