Each film he does one very public stunt for real; for the other stunt shots he does them as well, but not hanging off the side of a building or whatever, he's 5 inches off the ground with a landing pad in case someone slips. Remember that whatever is in the background was probably not there when the sequence was shot; background replacement is another "bread and butter" effect.
