The Julie Taymor-directed flick sets the Vietnam War, the Detroit riots and the civil-rights movement to the music of the Fab Four. We already brought you an exclusive photo and clips; now check out our handy primer on the film from our visit to the set.

From the colorful mind of director Julie Taymor ("Frida") comes "Across the Universe," a whimsical romantic musical told through Beatles songs. We've got your first look at the film with two clips, each featuring lead characters Evan Rachel Wood and Jim Sturgess singing a track from the Fab Four ("It Won't Be Long" and "I've Just Seen A Face" respectively). It's good stuff, so click here or on the below exclusive photo to check them out.
