* AlternateCharacterInterpretation - Is Falstaff some kind of [[CrouchingMoronHiddenBadass canny]] MagnificentBastard who [[SecretTestOfCharacter tests Hal]], and is eventually surpassed, or just an old fat drunkard who represents the worst excesses of Hal's youth -- who is eventually outgrown?
* EnsembleDarkhorse - Falstaff. To the point that OrsonWelles made a whole movie about him, and eventually ''Queen Elizabeth herself'' requested a play just about Falstaff -- ''Theatre/TheMerryWivesOfWindsor''.
* FanonDiscontinuity - Hal's first soliloquy, "I know you all", explains how he's not really a fun-loving rascal--he's just ''pretending'' to be one to make it more dramatic when he decides to get serious. A lot of the commentary on the play begins by carefully explaining why he doesn't really mean what he's saying.
** Of course, if you ''don't'' ignore the soliloquy Hal gives, then he's easily the best chessmaster in Shakespeare.
