Sci-fi franchise "The Matrix" will return for a fourth film with Keanu Reeves reprising his role as kung fu-kicking, shades-wearing hero Neo, studio Warner Bros said Tuesday. Lana Wachowski will helm the project, returning to write, direct and produce the latest installment of the hugely popular series, which has netted more than $1.6 billion worldwide, about humans trapped in a virtual reality by machines. ”We could not be more excited to be re-entering "The Matrix" with Lana," studio chairman Toby Emmerich said in a statement sent to AFP. Warner Bros did not specify if the new film would be a direct sequel, saying only that it was "set in the world of "The Matrix"," and did not give a release date.
