Harry Potter

A young man in a dark robe stands at the edge of a rocky arena, looking out at a crowd behind a wooden barrier, then turns and runs into the arena where he confronts a large, scaly dragon; the scene cuts to a man with wild white hair and glasses screaming in a cloud of smoke, then to a young man with glasses looking up in shock, and finally to a pale, faceless figure emerging from mist in a room filled with shelves of glowing blue orbs.
