Gary Busey, as he tends to, lends a certain authentic psychotic intensity to the role of Mr. Joshua, the blond chief enforcer of the criminal mercenary Gen. McAllister. The first thing you should probably know about Mr. Joshua is that he's wound a little tight, like a Ritalin kid with an automatic weapon. So you probably shouldn't laugh at his name. (Is Mr. Joshua really the best they could come up with? Did he used to be a talking owl that befriended children in a magical forest?)
At one point, at his boss's request, Mr. Joshua holds his forearm above a lit cigarette lighter just to prove how hard he is. (There's got to be a less permanently disfiguring way to illustrate this. Maybe a bench-press contest?) Later, when he is supposed to be sneaking around, he screams "It's fucking Christmas!" and shoots a TV set playing the old classic A Christmas Carol with his assault rifle. While it's unclear whether that moment was scripted, or just footage of Gary Busey at the on-set Christmas party, one thing is certain: Mr. Joshua needs to chill the fuck out.
Of course, he's on a collision course with Mel Gibson's equally crazy Det. Martin Riggs. The two maniacs finally go hand-to-hand on Danny Glover's front lawn in a frenzy of elbows and headbutts while a bunch of cops stand around and watch. (Hey, it's Los Angeles.)
