if you've never seen it on the big screen, here's your chance - City of Lost Children is this weekend's Midnight Movie at the Main Art Theater. Main at 11 Mile in Royal Oak.
you've already seen them all.
this is the trailer for a movie that premiered at SXSW in March. It's been called "the Mexican District 9", and it's getting a NYC/LA release in late October, with possibly more US cities after that.
