One of the writers of this was none other than Jeph Loeb!
Shout-Out: At least three of Arnie's lines are things he said in The Terminator. His one-word answer, "Wrong," before blasting away his first mook, his Catch Phrase "I'll be back" (of course), and the line, "Fuck you, asshole!" This was his first big movie after The Terminator and his first big movie with more than five lines.
Visible Boom Mic: Seen in the reflection of a car window when Bennett's vehicle drives away after dropping off Matrix at the airportnote In other words, after Arnold utters, "I'll be back.", along with the reflection of the boom operator in a lavender shirt.
The final fight between Matrix and Bennett was supposed to take place on an island that was in the middle of a naval exercise between the USMC and the USN (actually referenced by the radio chatter when Matrix steals the seaplane). Unfortunately, the film used up its special effects budget killing hundreds of mooks.
