One minute Joseph is sitting hopelessly alone in his cell, the next he's suddenly surrounded by colorfully dressed children, bright flashing colors, women singing how great he will one day become, men in white leather jock straps with close ups on their crotches, and Father Time wearing sunglasses and a lei. Suddenly he's sitting around alone in his cell again.
Also, Pharaoh Elvis, who sings one song (and its reprise) that, while incredibly catchy and setting up for Joseph becoming ruler of Egypt, is otherwise never referenced or mentioned again afterward.
"Benjamin Calypso". A tearful plea to not let their youngest brother become a slave, proof that the older brothers have changed... set as a faux-Hawaiian luau with grass hulu skirts and cheerful music? What?!
Ensemble Darkhorse: Several of the brothers can get this treatment, but the Pharaoh is especially popular despite his short stage-time. The narrator is also very popular because of the degree of her interactivity and sheer enthusiasm for the story and songs.
Epic Riff: There are quite a few throughout the show, but the very first (and the one which signals in the movie the movement from a silly low-budget school play led by a clumsy teacher to something truly awesome that will inspire the audience of students) appears at the very end of the Narrator's introductory song, when she strides down the aisle to let Joseph in for "Any Dream Will Do" and the special effects first start manifesting.
Heartwarming Moments: Joseph's reunion with his brothers, and especially the hug he gives Benjamin when he runs into his arms. Also, his reunion with Jacob.
Incredibly Long Note: Builds to this with each verse of Those Canaan Days ("where diiiiiiiiiiiid they go"), until the final verse. Played differently depending on the production - the movie has the brothers intentionally stop, glance around at each other, nod, then repeat the note. Most school productions will play this as holding the note so long they run out of breath.
Unintentionally Unsympathetic: Joseph can come off as this in productions that attempt to play the story completely straight. It's hard not to cringe as he casually belittles his brothers and rubs their father's favouritism in their faces. But whether or not this is "unintentional" can be debated: his subsequent traumas and struggles teach him humility to the point that he sings "I do not matter, I'm only one person" in prison. Most productions nowadays avoid this trope by playing up his boasting for laughs and making the brothers slightly more sympathetic.
Unintentional Period Piece: For a show that deliberately channels the styles of many different periods, the video is almost painfully a product of the 1990's, being on the popular 1990-1992-1994 productions that sought to speak to then-current audience tastes.
