When Hooker and Stacy are watching video footage of the Senator before the bomb exploded, the shot of the TV is a matte picture – i.e. the television set and the surrounding décor are a picture inserted over the film underneath. (Commonly used on TV and films; if a real TV was recorded, there would be strobing on the picture, though sometimes nowadays there are techniques where it is done).
Senator Grayle: I've learned a heck of a lot from you. I'd like to be team-mates with you again.
Hooker: I've learned a lot too, Stuart. I prefer the streets, they're clean.
Nembutsu: You're a dead man. I promise you.
Hooker: I'm easy to find.
Hooker: He's playing with dynamite, in more ways than one.
On the two-part version of this story, as with Part One, this episode credits all guest actors that appear in the story, not just in this particular part (for example, Yuji Okumoto is still credited, even though his character is killed near the end of part one).
