Ammer reports to Marvel Studios chairman David Maisel and will get to work immediately on campaigns for two of this summer's more anticipated releases, Iron Man and The Incredible Hulk.
The latter poses the considerable challenge of reviving interest in the superhero character given the much maligned release of Ang Lee's Hulk in 2003.
Ammer will liaise with Paramount on Iron Man, which kicks off the summer season on May 2, and with Universal on The Incredible Hulk, which is set to open on Jun 13.
Maisel hailed Ammer's 'tremendous marketing experience and expertise', while Ammer called the Marvel catalogue 'one of the most valuable and iconic character-driven libraries in the industry.'
Marvel recently launched its independent live-action studio to develop, produce, and fully finance features based on its renowned stable of characters. Among projects in development are Captain America, Thor and Ant-Man and Marvel is working with Fox on X-Men Origins: Wolverine, which is scheduled to open on May 1 2009, and with Sony on Spider-Man 4.
Ammer most recently served as an independent marketing consultant through his company G2 Consulting and before that was president of worldwide marketing for the Columbia TriStar Motion Picture Group and co-president of marketing in the Buena Vista Motion Pictures Group at The Walt Disney Company.
