Star Trek's latest chapter isn't just for Trekkies. Zoe Saldana and Alice Eve's promo tour has already been proof of the glamour on Star Trek Into Darkness's red carpets. But last night's premiere got quadruple the celebrity-style treatment when Kate Beckinsale and Jennifer Morrison joined the film's leading ladies in LA. Jennifer channeled Disco-era dazzle in a sequined jumpsuit, then polished it off with nude platform pumps and a pair of major jewel-drop earrings. Kate took a more subtle approach in a riff on the classic LBD, a strapless and asymmetrical-hemmed dress from Alberta Ferretti, which she amped up with a playful pair of neon sandals. As for the night's costars, Zoe Saldana bared her midriff in a ruffled, nude peekaboo confection from Rodarte's Fall '13 collection and Alice Eve slipped into a sleek gold and black sheath from Zuhair Murad. That's the rundown on who wore what; now it's time to cast your vote.
