Irvin Kershner, the director of The Empire Strikes Back, appears as a director during the Aegis Oil commercial scene.
Money, Dear Boy: The only possible reason that Michael Caine appeared in this film. And it is. Around that time, he couldn't find many opportunities for work so he took what he could. Also the only possible reason they could have gotten R. Lee Ermey to be a moron here. And Joan Chen must have needed some money too...
Old Shame: Michael Caine, arguably. He needed work in the 90's and did it since it was a job. Seagal and Caine reportedly did not get along either, with Seagal (never really known for his "acting" - and that's putting it generously) reportedly talking down to Caine (who at the time had one Best Supporting Actor Oscar to his name with three nominations for leading roles) all throughout shooting.
