Are comic books now the way for writers to crack open Hollywood's walled garden? This Wired Magazine blog says that comic-based movies saved Hollywood this summer. The article previews some the upcoming movies. However, for a comprehensive list of upcoming films, the Den of Geek is the place to go. They suggest that comic books, rather than speculative scripts is the way to a movie option. Their list is a compelling argument. Um, I've never been much of a comic book fan, but I might see (will see) Sherlock Holmes (2009) and yeah, The Avengers (2011). If it's in a theater near me, then Wonder Woman.

Wikipedia has a list of past comic-based films in the English language. (I checked there hoping hoping hoping that Nancy was not in the list. It wasn't.) If you want a worst-to-best list with nice graphics, then visit Rotten Tomatoes, but you'll have to click till it hurts to see them all.
