This month members of the American Federation of Musicians picketed the Screen Gem studios in Wilmington, N.C., where Marvel (a Walt Disney Co. subsidiary) is shooting “Iron Man 3.” AFL-CIO, the federation of labor unions, reports AFM musicians are upset because Marvel Entertainment “takes millions of taxpayer film production incentive dollars and then offshores the musical scores in foreign countries under sub-standard conditions. Their latest blockbuster, The Avengers, was filmed stateside with $30 million in tax rebates, but the company fled to Europe to record the film score, escaping payments to musicians’ pension, health care and residual funds.”Captain America himself might call this un-American.
