Lily Collins leads the movie playing Clary Fray, a young girl who discovers she has the power to see Shadowhunters, but most importantly, the British one who likes to speak in riddles. Turns out Clary can see between worlds or something, which seems to involve hanging out at raves and battling otherworldly beings in hotel banquet halls with crossbows and shooting beams out of the palm of her hand. Or something. A prequel is already in development, which is cute and all and is par for the course these days, but we'll see if that actually happens.
'Mortal Instruments' arrives on August 21st.
