A Sound of Thunder is a 2005 sci-fi movie loosely based on the Ray Bradbury story of the same name.
The movie contains examples of:
- Adaptation Expansion: Turning a short story into a feature film might be a good cause for the awfulness.
- Adaptational Species Change: In the book the main dinosaur was a Tyrannosaurus rex, while here it's an Allosaurus.
- Artistic License – Biology: Where do we start!
- Baboonasaurs, that's where. Alternately "Baboonizards." There's also the flying "Batboonizards," and "miscellaneous underwater shark-eel-thing."
- And we continue with the claim that lions are descended from Allosaurs. Congratulations. Perhaps they meant "fill a similar ecological niche", but bungled it.
- The claim that humans were "the last species to evolve." That's... nowhere NEAR how evolution works.
- Cutting Corners: The whole situation started because of a "perfect storm" of 1) somebody panicking and stepping off the path and 2) Haddon shutting down the time machine's bio-filter (which would have prevented this) in order to save money on electricity.
- Delayed Ripple Effect: Taken to ridiculous extremes. Translucent blasts called timewaves come out of nowhere and start knocking people around. And each time they do more species become "devolved".
- Dull Surprise: "Pierce Brosnan was originally slated to star. Unfortunately, he was replaced by a wooden marionette that looks a lot like Edward Burns." (It's a running gag on the recap seeing how his facial expressions are the same for most of the film.)
- Plot Hole: If the time waves cause existing organisms to de-evolve (we know this because that one female character turns into a white lemur thing at the last wave), and all animals were extinct by 2055 then where did the originals come from?
- Sexy Man, Instant Harem: Ryer bangs a client.
- Shout-Out: Haddon kiss-assingly compares his clients to "Columbus discovering America. Armstrong stepping on the moon. Brubaker landing on Mars". The latter is a reference to Capricorn One, Hyams' debut film, where Brubaker was the captain of a faked Mars landing.
- Tagline: "Evolve or die" and "Some rules should never be broken".
- Voodoo Shark: Apparently the reason big-game hunters are so eager to go back in time to hunt dinosaurs is because... wait for it... all animals are extinct in 2055. This is mentioned in one scene and then never referenced again, and doesn't explain why people wouldn't be willing to pay to use time travel for more peaceful sightseeing purposes ... or to retrieve healthy animals from the past and repopulate the Earth with them, for that matter.
- You Get What You Pay For: The boss of the safari company shutting down a key component of the time machine to save power contributed to the catastrophe at hand.
