It looks like Daniel Radcliffe's stuntman was seriously injured doing a harness-flying stunt. We actor-combatants and aerial dancers here at Bonzuko send good thoughts and best wishes for a full recovery.
Check out this article about the incident; it sounds pretty bad. Apparently he's worried his career as a stuntperson may be over. The article reiterates what we've been writing here about the dangerous art of falling: "...no matter what precautions are taken, performing stunts always carries a risk."
