harvest films, in partnership with GolinHarris, produced an online summer campaign called the Klondike Celebrity Challenge featuring actor Joel McHale of “NBC’s “Community”. The interactive launch, directed by Tristram Shapeero, is prompting Facebookers and Tweeters alike to devise challenges for three surprise celebrities to perform for a Klondike Bar. The contestant who submits the best challenge will then have to perform the same scenario or challenge as the celeb. The first star is Alfonso Ribeiro from “The Fresh Prince of Bel-Air.” Other mystery stars will be announced throughout the summer. Things could get weird… What would YOU do for a Klondike Bar?
