This consists of interviews with the cast and crew, all of whom have something compelling to add within their area of expertise(and there is a very clear love of what they're working on), clips from the movie, behind-the-scenes footage, and incomplete effects shots.
It's 4 and a half minutes long. This is found on the second disc of the special edition DVD release of Predator.
They talk about characterizing via props, such as the specific weapons used by the individual leads. Duke's knife and razor. Chaves' grenade launcher. Black points out how little it makes sense, him being equipped with a red beret(which he was allowed to get rid of) and the wide-rim glasses(rather than goggles), and why he got to tell the two jokes he did.
I recommend this to any fan of the property. 8/10
