MLive is reporting that X-Men: First Class will shoot some scenes in Michigan and a call for potential locations has gone out:

"West Michigan Film Office: "A location scout is seeking out areas with a 1960's, South-American or Central American island feel for the next X-Men movie, 'X-Men: First Class.' In particular, he needs to find café and bar locations, evoking the Argentinian feel of Bariloche, and an Art Deco Cafe or restaurant overlooking a body of water. Additionally, the movie calls for a Miami styled harbor for yachts. If you know of any locations that seem to match a description, please contact our office."

X-Men: First Class also plans to film in London in September.
