Although Spider-Man has had some of his most successful movie outings as part of the Marvel Cinematic Universe, the fact remains that the cinematic rights to the character are owned by Sony, rather than Marvel Studios parent company Disney. A dispute between the studios over the financing of future Spidey movies led to reports this week that Marvel Studios president Kevin Feige will no longer serve as a producer on future Spider-Man films. Now Sony has commented directly on the issue.
In a series of tweets, Sony claimed that many of the reports about the dispute have "mischaracterized" discussions between the studios. The statement focuses on Feige's involvement, but clearly places responsibility for the decision for him not be involved with Disney. It also makes a clear reference to "IP they do not own," emphasizing that, ultimately, Spider-Man is Sony's property as far as movies are concerned.
