In spite of an effort by its releasing studio to circumvent critics (and despite an ad campaign in which star Charlize Theron's nudity was heavily implied), Aeon Flux failed to flex much of a latex-clad muscle at the box office this weekend. With an estimated three-day gross of $13.1 million, the cartoon-inspired action flick barely edged out Walk the Line for second place, but fell far afield of Harry Potter's first place, $20.5 million take. This is Paramount's second attempt this fall to create synergy with lil' sister MTV, and the second to disappoint; Get Rich or Die Tryin' has, four weeks after its release, all but disappeared. It's also Theron's second film this fall, after North Country, to make little impact at the box office. Meanwhile, Transamerica more than quadrupled Aeon's per screen take at two locations; it goes wide on Christmas day.
