In the wake of its dispute with book publisher Hachette, Amazon is now in a standoff with Warner Brothers. As part of a confrontation with the film studio, Amazon is blocking pre-orders of Warner Bros. films like "The Lego Movie." The move pertains to Warner Bros. films on DVD and Blu-Ray discs, while streaming versions appear to remain available through Amazon Instant Video. Amazon has not commented on the business dispute, but according to reports, it stems from the company's desire to seek better financial terms for the discs it sells. The New York Times reports that Amazon refused to pre-order the upcoming films in mid-May as an agreement with the studio could not be reached.
