The Stallone-Schwarzenegger jabs continue. In Slater's world, Stallone is The Terminator. Danny cannot believe it. More directly, the fact that F. Murray Abraham played Salieri in Amadeus is mentioned, then it becomes a plot point.
Danny even lampshades it twice, both in the police station. The first is when Robert Patrick walks out of a police station in his Terminator police uniform; the second is a real plot point when F. Murray Abraham turns up as Jack's Remember the New Guy old cop buddy- Danny warns Jack not to trust him because "he killed Mozart", because he knows that Murray is always typecasted to villain roles and he's right; he is The Mole. But he doesn't remember killing "Moe Zart".
