stuntman?? actor??

i was preparing to act in ascene. no clue was i either the stuntman or actor. but the location was some abandoned house. i was taking a walk around the location and saw some props for booby trapping from 2nd floor to the first. then i told the prop technicians, "hey is that a land flame mine? that's not how you guys should do it, here let me show you how" and i taught them the more accurate placement. contributing from my army days, i figured the prop should be more accurate and it didn't have the boosters required to open up the container. just didn't quite make sense.
