shareBomb Defusion. It's one of the hardest thing to portray correctly in movies.
In movies, virtually any kind of bombs can be defused. While in reality, most can't. They would just move it out to a safer location, or covered it up, then shotgunning it until it controllably explodes.
Most movies unecessarily feature a bomb with timer ticking and red and green cables to cut. Which is totally fiction.
