David Maisel, who helped to secure the funds that allowed Marvel to finance and produce its own films, will step down as chairman of Marvel Studios once Disney's purchase of the company wraps up on Dec. 31.
He will remain as an executive producer of Iron Man 2, The First Avenger: Captain America and Thor, and is poised to make $20 million when the Disney deal closes.
Maisel, who joined Marvel in 2003, helped to raise the $525 million that enabled the company to produce its own movies rather than simply license its characters to film studios. He also played a key role in early negotiations that led to Disney's $4-billion acquisition of Marvel.
After the merger, Marvel Studios President Kevin Feige will report to Rich Ross, who was named chairman of Walt Disney Studios in October.
