-->'''Ralph:''' Well, we did it.\\
'''Richard:''' Yeah, we did it... we brought [[StuffBlowingUp civilization]] to Planet Nova.

'''King Dinosaur''' is a 1955 SciFi BMovie produced by Robert Lippert (known for ''Film/RocketshipXM'', ''Film/LostContinent'' and ''JungleGoddess'') and filmed in three days by quickie king Creator/BertIGordon.

The story is predicated on the notion that a new solar system has set up shop "a half-year's rocket flight away" from our own. A group of intrepid scientists turned space travelers -- "zoographer" Richard Gordon (Douglas Henderson), mineralogist Nora Pierce (Patti Gallagher), physician Ralph Martin (Bill Bryant) and chemist Patricia Bennett (Wanda Curtis) -- blast off (via stock footage of Germany's V-2 rocket) to explore the earth's new neighbors.

Upon landing on one of the planets (actually the mountains surrounding Los Angeles) the scientists confront all manner of outsized reptiles (courtesy of clips from ''OneMillionBC''). When the planet's "dinosaurs" threaten our heroes, the huge lizards are dissipated by an atomic-bomb blast (more library footage). Having made the planet safe for colonization (?), the space travelers return to Earth.

!!''King Dinosaur'' provides examples of:
* AllPlanetsAreEarthLike: The only apparent difference is the bacteria.
* ArtisticLicenseBiology: The "giant bee" is actually an Orthoptera, probably a [[http://en.wikipedia.org/wiki/Jerusalem_cricket Jerusalem cricket]].
* ArtisticLicensePaleontology: Dick notes that the giant iguana is identical to the tyrannosaurus rex. Um... no?[[note]]'''Servo:''' ''(firmly)'' That's an iguana from Pet World.[[/note]]
* ChekhovsGun: The atomic battery.
* ClothingDamage: Both Ralph and Nora get some of this in separate animal attacks; but Dick tops everyone when he has to [[ShirtlessScene tear his entire shirt off]] to make a tourniquet.
* DeathBySex: Subverted twice over, in that they don't die and they didn't even get to the sex -- but it's a close call on both counts.
* DeusExNukina
* EverythingsWorseWithBees: Especially giant, superimposed bees.
* HardWorkMontage
* ItsAllMyFault: Ralph's near death-by-croc comes as a side result of his and Pat's sneaking off to snog in the night. Pat is so distraught by this that she is [[NeutralFemale unable to help patch him up afterward]].
* {{Jerkass}}: [[MeaningfulName Dick]] spends a lot of time pushing the women around -- literally. [[Series/MysteryScienceTheater3000 The 'bots]] call him out for this.
* [[StuffBlowingUp Lizards Blowing Up]]
* MightyWhitey: It's a TheFifties sci-fi BMovie, so it's fairly inevitable.
* NeutralFemale: Invoked and enforced by Dick; when the ladies volunteer to share night watch duties, he quickly shoots the idea down. Of course, Dick seems GenreSavvy because given a chance to act, they both panic.
* NoAnimalsWereHarmed: Very clearly averted, particularly in the "iguana vs. crocodile" fight.
* OmnidisciplinaryScientist: Not so much for their respective scientific fields per se (although the zoologist does a good job doctoring up the doctor), but rather the mission as a whole; note the rocket's complete and total lack of '''astronauts'''.
* PseudoCrisis: Several:
** Ralph is attacked early on by a crocodile and injured badly; however, he's pretty much fully recovered within a few scenes (two days' time, in-story). After that, his weakened state becomes essentially an InformedFlaw.
** The giant bee; they simply shoot it dead -- although it did take a lot of shots.
** At one point, a snake slides and shimmeys across a sleeping Ralph's body while Dick looks on helplessly. After a minute, the snake gets bored and departs of its own volition.
* ReptilesAreAbhorrent: And not just the giant ones; Pat very nearly has a complete meltdown when a snake gets fresh. [[note]]To be completely fair, of course, lots of folk have strong snake phobias.[[/note]]
* ScreamingWoman: For cryin' out loud, Pat!
* ShirtlessScene: Dick needed to wrap a wound.
* StockFootage: Not unlike ''Film/TheDeadlyMantis'' (which would feature in MST3K some years later), ''King Dinosaur'' opens with about ten minutes of stock footage. Unlike the latter, however, here the stock footage is actually relevant to the story at hand -- it details construction of the rocket which will take the scientists to Planet Nova.
** The stock footage also includes a callout to the [[ChekhovsGun atomic battery]] and its explosive potential.
** The giant bee is clearly taken from another film, seeing as it never appears in the same shot as the characters.
* ThereIsNoKillLikeOverkill: In order to outrun a giant iguana, the scientists... plant an atom bomb. Makes sense.
* TitleDrop
* UnusuallyUninterestingSight: One of the scientists cheerfully says that she doubts they'll see any monsters - just after they'd been attacked ''by a bee the size of a car''. FacePalm.
