Crazy Awesome: Professor Layton flies a helicopter, which he built out of random parts in a shed, up a massive robot. It gets destroyed by the robot, but he jumps off it, pulls himself up to the robot's top, has a swordfight with Descole, using a piece of piping instead of a sword, stops to play an organ, raises a kingdom out of the sea, goes back to fighting, blows up the robot by accident, and gets off completely unscathed.
For the movie itself; not only can the audience solve the formal puzzles set for the characters along with them, but most of those scenes use remixes of the puzzle themes from the games. The music even marks the time limit for the first two!
Without spoiling too much, at one point, Layton plays two parts in a three-part harmony at the same time. If that's not a musical CMoA, this is not a world worth living in.
Nana Mizuki is Janice's seiyuu. In the movie (especially the end credits song) she shows an impressive vocal range, even if the songs all do have the same basic tune.
The Remix of Descole's theme.
Luke finally gets his own Leitmotif, and wow did that boy earn it.
