Twentieth Century Fox and Marvel Enterprises have resolved their differences concerning the syndicated television series MUTANT X. Terms of the settlement were not released but have been amicably resolved according to a Fox statement and both sides are looking forward to expanding the relationship. Fox produced the X-MEN film in 2000, based upon the original comic book characters. A sequel is scheduled for release this year. In April 2001, Fox had filed suit against Marvel, syndicator Tribune Entertainment and producer/international distributor Fireworks Entertainment, alleging that MUTANT X violated Fox's exclusive rights to Marvel's popular X-MEN character group. Marvel countersued, asking the court to dismiss Fox's claims and argued that the TV series used different characters. A federal judge in New York ruled that the series could proceed as long as no reference was made to the original X-MEN comic books, characters or the Fox feature. The judge did allow Fox to pursue a breach of contract claim. Marvel's suit with Sony Pictures Entertainment over SPIDER-MAN is still ongoing.
