Detroit has served as a great backdrop for some amazing films in the past few years. You might remember Ryan Gossling spotting while he was filming “How to Catch a Monster,” and Michelle Williams spent six months in Metro Detroit while working on “Oz: The Great and Powerful.” And this summer, Ben Affleck and Jennifer Garner have announced they plan to move their family to the Motor City while he films the yet-to-be-named sequel to “Man of Steel.” Already there have been spottings of Henry Cavill, who will be playing Superman, as well as Director Zack Snyder.
