Accidents have hit the set of Guy Ritchie’s take on Sherlock Holmes. The Sun reports that Robert “Iron Man” Downey Jr. was knocked out accidentally by seven-foot British actor Robert Maillet after catching a hook to the chin.

“[Downey] went flying and was out cold… he didn’t want to go to hospital and kept trying to get up,” reads the report. The actor was revived by medics and needed stitches inside his mouth.

Other reports circulating on the web note that the set was closed for two hours when a tanker making a delivery burst into flames.
