Marvel Entertainment Inc., maker of the movie “Iron Man,” and comic-book creator Stan Lee were sued by Stan Lee Media Inc. stockholders over ownership of assets including “Spider-Man” and “The Incredible Hulk” characters.

Shareholders including Jose Abadin and Nelson Thall, suing on behalf of Stan Lee Media, asked for damages of $750 million in a complaint yesterday in Manhattan federal court.

They claimed they were harmed after Marvel and Lee improperly transferred ownership of Lee’s creations from Stan Lee Media to Marvel.

“Most of Marvel’s financial success, including from the films, comes out of assets created by Stan Lee that are the subject of this suit,” the complaint says.
