The Puzzle states explicitly "Black to Move", so Black actually has the first move.
Anyway, Stockfish has found that the optimal play is in fact the path you were talking about.
Stockfish only declares "Checkmate" if it is impossible to avoid, so that's the optimal moves. Not quite what the original Youtube Video said, so I guess the puzzle is a little bit flawed. Still, it seems like a "reasonable position" that satisfies all of the drama needed for the film.
First Strike +1/+1 and Indestructible.
