A live action movie based on the original ''WesternAnimation/{{Underdog}}'' animated series, that was made in 2007 by the Walt {{Disney}} Company. It tried to reinvent a FunnyAnimal cartoon as a snarky comedy starring an actual dog. It bombed at the theaters.

A small police dog (fired for his terrible sense of smell) is captured by the MadScientist Simon bar Sinister to make experiments on. These grant the dog superpowers and it escapes. It is found by a retired cop and his teenage son; the boy discovers the dog's secret and convinces him to become a superhero under the name Underdog. But bar Sinister is looking for him to try to gain the powers for himself.

!!Underdog provides examples of:
* AnimalTalk: Animals understand each other, and can understand humans, but only Shoeshine can speak when he has his powers.
* AnimalSuperheroes
* ArmorPiercingQuestion: Underdog says two things to Barsinister's German Shepherds that push their TheDogBitesBack moment.
-->Has he even given any of you a name?
-->Who is he to call you worthless?
* BadBoss: Barsinister. {{Lampshaded}} by Underdog: "If he was a better boss, he'd be able to afford a higher quality sidekick!"
* BatmanCanBreatheInSpace: Underdog gets hurled out of Earth's atmosphere by the bomb he buries, but that doesn't make any difference.
* BigBad: Dr. Simon Bar Sinister
* CatchPhrase:
** Invoked with bar Sinister's "Simon says..."
** Also, after Jack tells him he needs one, Underdog goes through several, winding up with "There's no need to fear; Underdog is here."
* ChekhovsSkill: Shoeshine's bad sense of smell. And his frisbee-catching, [[RuleOfThree and his super-speed digging.]]
* ClarkKenting: ''Nobody'' recognizes Shoeshine despite not even wearing glasses.[[note]]To be fair, a lot of dogs look alike to people. And one civilian ''does'' note the resemblance. This doesn't excuse that Polly can't tell the difference, despite Shoeshine not even changing his voice as Underdog.[[/note]]
* ConeOfShame: Underdog wears this to avoid being recognized.
* DeadpanSnarker: Several characters, but notably Shoeshine and Bar Sinister.
* DepravedDwarf: Simon of course
* DisneyDeath: [[spoiler: Underdog]], at the end.
* DoWrongRight: One of Jack's teachers when he attempts to skip a class: "I don't know why I'm more disappointed - that you forged a note to get out of class, or that you did it so poorly you couldn't fool a high-school gym teacher."
* TheDragon: Cad Lackey although he thinks he is in a BigBadDuumvirate with Dr. Simon Bar Sinister.
* GoingForTheBigScoop: Polly Purebred's owner, Molly, evokes this, and runs into the same kind of trouble.
* HerosFirstRescue: Shoeshine saves Molly and Polly from muggers.
* HeroicDog: Who do you think?
* HumanFocusedAdaptation
* [[IHaveYourWife I Have Your Family]]: Barsinister pulls this on Underdog. Given that Underdog is an {{Expy}} of Superman, this worked about as well as you would expect.
* IJustWantToBeNormal: Shoeshine.
* InNameOnly: Well, it uses some of the names from the cartoon. Everything else is different.
* InsistentTerminology: Barsinister is Cad's "partner", not his "boss".
* IronicEcho: "I prefer the term 'visionary'".
** "It will only hurt a lot."
* LovesMyAlterEgo: Shoeshine has the same problems as the early Clark Kent did getting his LoveInterest's attention.
* MadScientist: And is named so by the supporting [[TheCloudCuckooLanderWasRight crazy hairless dog]].
* MistreatmentInducedBetrayal: Barsinister's German Shepherd minions, who turn on him when they realize that he sees them as tools and not as "sparkling individuals."
* MythologyGag: Underdog's secret identity is named "Shoeshine". In the original cartoon, Underdog's secret identity was as a [[ShoeShineMister shoe shine boy]].
* NiceJobFixingItVillain: While Barsinister's German Shepherds might have listened to Underdog anyway, Barsinister didn't help his case by calling them "worthless mutts".
* ReactiveContinuousScream: "Give the dog your food!" "...AAAAAAAAAAAAAAAHHHHHHHHHHHHHHH!!"
* RhymesOnADime: Shoeshine, as Underdog.
* SecretIdentity: Of course.
* ShoutOut: Lots.
** Several to the ''Film/{{Superman}}'' movies.
** One to the sequence in the first ''Film/{{Spider-Man}}'' movie where the hero gains his powers. And the second one, in the scene with Cad impersonating an old lady while hanging from a building, with an American flag no less.
** Bar Sinister is a Small Person version of DoctorDoom, complete with scarred face.
** [[ComicBook/FantasticFour "It's clobbering time!"]]
** Dogs on a date batting meatballs back and forth? Lady and the Tramp.
* TitleDrop: Given that the movie's title is the hero's ''name'', it happens all over the place.
