Unless Monty the Magnificent was also a government law officer (ie. a cop) then no, its not entrapment in a legal sense. At least not in the United States.
I do believe however you could easily get the charges reduced to "involuntary manslaughter " or even dropped on the agrugement that you believed this was just part of the show, and did not believe your actions would result in the man's death or injury. There is actually something to be said for plausible deniability. Through, being in a cemetery with a gravestone that reads "I turned you into a murder" might hurt your cause on that front quite a lot.
