Brief Bay Comments on Bumblebee
astf director Michael Bay has weighed in, quite briefly, on the reasoning behind Bumblebee's vehicle mode in the movie. In this thread at Bay's Shoot For The Edit forums, that site's admin Nelson says Bay is downplaying rumors that 'Bee isn't a Bug because of Volkswagen's supposed reluctance to be associated with the film. Instead, he says it's an effort to keep Bumblebee from being associated with Beetle/movie star Herbie the Love Bug.
