Fair warning: This is a slight, trivial, and practically meaningless piece of upcoming movie news -- but it touches on three things we love here at Cinematical: Action movies based on cartoons based on ancient marketing campaigns, horny directors, and fake breasts. Here we go:

According to SFGate's Hot Dish blog, sexy actress Sienna Miller was forced to wear fake hooters so as to accentuate her cleavage in the upcoming G.I. Joe movie. Ms. Miller will be playing The Baroness, and apparently her god-given boobies were not adequate in the eyes of director Stephen Sommers. ("'I'm gonna be honest, I like girls with big boobs," is what the director told her. Strange comment from a guy whose leading ladies have been Famke Janssen, Rachel Weisz, and Kate Beckinsale, three gorgeous women who aren't exactly D-cups.)

Ms. Miller notes that she was "mildly offended" by the breast issue, and I'm kind of surprised that the topic didn't come up before her first costume fitting, but hey ... The Baroness is pretty stacked. Perhaps Mr. Sommers is just trying to remain faithful to the source material -- or yeah, maybe he just likes big boobs. Lord knows the target demographic for G.I. Joe loves boobs. Check out images of Sienna as The Baroness in the gallery below.
