Scooby-Doo! Stage Fright is the 20th title in the made-for-video Scooby-Doo series. It was due out August 20, 2013, but had its television debut on Cartoon Network on August 10, 2013.Fred and Daphne are finalists on a show called "Talent Star", which is being telecast from an opera house haunted by a vengeful phantom. The suspects include a pint-sized singer with over-pushy stage parents, a magician, and a garish diva.
All Love Is Unrequited / Unresolved Sexual Tension: Daphne confides to Velma that the time spent with Fred preparing and rehearsing their song for the talent show has made her fall in love with him, but she doesn't have the nerve to tell him up front.
During the ending credits, Daphne again talks with Velma while Fred (fueling the van) talks with Shaggy and Scooby wondering if the kiss during their performance was either simply part of the act or do they really like each other that much. Their friends' response:
Velma: How many times do I have to say it? Just talk to him!!
Shaggy: Like, how many times do we have to say it? (with Scooby) Just talk to her!!
Brick Joke: After beating and catching one of the phantoms, an officer offers to drive the gang back to the show, stating he had bet $50 on Fred and Daphne to win. When the two throw the contest and the last phantom is caught, that same officer angrily tells the pair they owe him fifty bucks.
Busman's Holiday: Once again, the gang is trying to do something totally unrelated to mysteries when a ghost pops up and they have to unmask him. This time, the gang just goes with it - it even gets a lampshade at a few points.
Car Chase: The gang get into one with one of the Phantoms. It's massive.
That Rita Repulsa-looking singer is one for La Carlotta—the Phantom even does the "change the throat spray" trick from the 2004 movie.
Fanservice: Nothing too strong, but about as close as this series gets - There the hotel scene where Daphne is sorta posing on the bed rather cutely with her shoes off. And shortly after there's a scene at night with Daphne and Velma where the latter is wearing nothing but a long shirt and socks and the former is wearing lingerie.
Foreshadowing: The techie in the control booth cries out "He's everywhere!" when asked to report the Phantom's location from the closed-circuit cameras. There are four costumed Phantoms, plus a fifth who manifests only via the AV equipment.
Gambit Pileup: There are four phantoms actively attacking the show at the same time, each with their own criss-crossing objectives and entrance into the plot. It gets a little confusing as to who is doing what and when - and in a stroke of Fridge Brilliance it muddles the plot enough that the audience (expecting one Phantom) doesn't know who to latch their suspicions onto.
The first and possibly "main" Phantom to appear was Crissy's father, who was out to sabotage the other contestants so that Crissy would win. This is the "CRISSY MUST WIN" Phantom.
The other main Phantom is Dewey Ottoman, who moonlights as a high-profile thief and is using the whole thing as a cover so he can steal a diamond while the cops are distracted. This is the lemon-scented Phantom.
Mel Richmond is attempting to burn down the Opera House to collect the insurance and get rid of the drain on his finances. Notably, he only started doing this well after the first two Phantoms began their sprees (if not the very scene he was caught) and was merely using the opportunity to avoid suspicion.
Brick Pimiento was the Phantom at some point as well - however, we only see him suit up and never get any elaboration on what he did or when. Again, he seemed to have been using the opportunity, so he started later.
Honor Before Reason: Fred and Daphne win the contest through number of votes, but they choose to throw the contest on behalf of a sweet little girl who was a contestant, a violin prodigy. Fred and Daphne's score gets drastically reduced when they start telling corny jokes.
Justified, if Emma, the little girl, won the contest she could save her parents farm with the prize. Fred and Daphne however couldn't think of a reason for needing the money.
Lampshade Hanging: Shaggy gets a great instance of this when told that there's rumors about the Opera House being haunted.
Shaggy:(casually) Of course it's haunted. When do we ever go anywhere that's not haunted?
Daphne: "Fred, why do ghosts and monsters show up wherever we go? Is it something about us?"
Fred: (as if it's obvious) "No, this happens to everyone."
Fred: "It would just be too much of a coincidence if it just happened to us, so logically everyone must run into ghosts and monsters all the time."
Legacy Character: The original Phantom bedeviled the Opera House back during it's "disco hall" phase in the 70's. Though they meet the original Phantom at some point, the slew of Phantoms these days are pulling Copycat Crimes for various reasons.
Nice Girl / The Pollyanna: Emma loves everybody, is extremely kind, very sportsman-like (especially in contrast to the other contestants), makes instant friends with Fred and Daphne and even seem to be rooting for them at some points. She and her folks are such incredibly good people that the viewer seem almost expected to think it's an act and one of them is the Phantom, especially after we find out that they need to win the competition to pay off their debts. It isn't. They really are that good.
Obfuscating Stupidity: Not stupidity per se, but Dewey Ottoman seems to exaggerate his germ obsession and puts forth a frail, neurotic disposition - including fainting several times at the mere mention of the Phantom. As a result, the gang agrees that he's creepy but don't seriously consider him as the Phantom. Boy are they wrong - turns out he's an international thief, and during the final Car Chase though he's still foppish and clean he drops the act almost entirely. He even gets covered with gunk and trash several times and outright ignores it in his pursuit of the Soap Diamond.
Only Sane Man: Velma among the gang, as usual. Waldo and Emma among the contestants.
Perky Goth: The green haired member of Girlasaurus Rex. The other members are pretty perky as well, but are a little bit better at hiding it. Slightly.
Green Haired Girl: (high pitched giggle) "Omigosh. We are so metal!"
Red Herring: Played with, as it turns out there are at least four phantoms running around each with their own reason for donning the costume an terrorizing the show, which includes nearly every obvious suspect and one who wasn't so obvious. Only one of them turns out to be harmless (well at least in this decade anyway).
Running Gag: Daphne poorly hides being in love with Fred, to which Velma rolls her eyes. Culminates in an entire scene of Daphne being melodramatic and Velma being a mix of supportive and sarcastic.
Shaggy and Scooby attempting to wow Brick Pimiento with a lame act. Brick initially makes the mistake of encouraging them, then eventually starts calling security.
Shaggy and Scooby's inventive ways of sneaking Scooby past the security guard.
Scooby-Doo Hoax: Inverted and played straight. The main Phantom and one of the others aren't trying to scare people away from the opera house, but are either a) trying misdirect the police's attention in aBatman Gambit so that they're all watching the Opera House at the time of his diamond heist or b) trying to get publicity for the show and actually attract people. The original Phantom, way back in the 70's, was attempting to do this however (and succeeded).
Screw This, I'm Outta Here!: Waldo outright walks out on the show after the Phantom attacks one too many times. Girlasaurus Rex follow him out when their instruments are sabotaged, and the The Great Pauldini follows suit a few hours later.
Let's face it. The entire thing was filled with Phantom of the Opera references, even having a disco ball as the alleged chandelier.
Terrified of Germs: Mr. Ottoman, the guy in charge of the competition. Turns out to be what gives him away as one of the Phantoms. The lemon scent that Shaggy and Scooby picked up during their encounter with the Phantom was probably his floor polish.
Shaggy is a downplayed version of this trope. His cowardliness is much less noticeable here than in most other parts of the franchise as he is actually putting himself in danger to help get things done and keep others safe. He also feels more competent in this movie as he goes out of the way to do things himself without having to be told or bribed with Scooby snacks.
Think about this: Dewey Ottoman is a cowardly germophobe at the beginning of the movie. But later during the car chase, he manages to weave his way in and out of Chicago traffic, always stay one step ahead of the gang, and makes a complete and utter leap of faith from his trashed car before it goes tumbling off the bridge and blows up.
By association Scooby, as his and Shaggy's fearfulness go hand in hand.
