For the second time in two months, Warner Bros. has agreed to pay at least $ 1 million for an action script by writing duo Larry and Andy Wachowski.Their virtual reality-themed spec script “The Matrix” had been on the street for just a few weeks when WB took the inside track last month and beat at least two other majors to the punch. The deal, which is closed barring a few details still to be ironed out, was negotiated for the Wachowskys by their Gotham-based reps Rajeev Agarwal and Lawrence Mattis of the Circle of Confusion Ltd. agency. The “Matrix” story is described as an action/adventure piece set in a futuristic world created by computer, much like an updated “Tron.” “Matrix” is the name of this alternate virtual-reality universe and refers to a shape within which some form of life or information grows. Sources said the plot incorporates several high-tech combat elements, as in “Terminator 2: Judgment Day,” and also will make use of available VR technology. As reported (Daily Variety, Dec. 10, 1993), WB also is believed to have signed the writing team to work on several of the studio’s action-oriented scripts.
