Breakaway Pop Hit: "Late Goodbye" by Poets Of The Fall, played during the credits roll of the second game and repeatedly sung by characters or played on piano throughout the game.
And a lot of the Cleaners, their Mook coworkers, and the brother from "Lords and Ladies" are the goddamned Batman.
The Other Darrin: Series writer Sam Lake modelled for Max in the first game but was replaced by the irreconcilably different-looking Timothy Gibbs in the second, owing to the project's bigger budget (see Progressively Prettier). Lampshaded in one of the second game's fourth-wall-breaking dream sequences, when one of Max's doubles looks at himself and says "I've been switched! I didn't used to look like this!" Additionally, James McCaffrey (as Max) was the only actor to reprise the role for the second game.
In addition, Max's likeness in the third game is now being modelled after McCaffery's likeness, himself looking noticeably different from Timothy Gibbs as well as having his voice again.
