Limited edition dark chocolate M&Ms; played a role in a Star Wars Episode III marketing campaign. The company received over 30,000 e-mails requesting the permanent return of dark chocolate so they’ve now added it to the growing M&M; arsenal. The ad campaign ignores pop culture in favor of Expressionism. M&Ms;’ parent company is offering a reward of two million dark chocolate M&M;’s for the return Edvard Munch’s “The Scream,” stolen from the Munch Museum two years ago. White chocolate fans can grab a bag of “Pirate Pearls”, M&M;’s movie promotion for Pirates of the Caribbean.
