- Cast Incest: AnnaSophia Robb and Alexander Ludvig dated at one point after playing brother and sister.
- Hilarious in Hindsight: Four years prior, Carla Gugino starred in the television series Threshold, in which she played an The Men in Black-type similar to Henry Burke.
- Idiot Plot: The kids have to retrieve some technology from Earth to save their planet, so rather than send scouts to find this technology, the aliens send a bounty hunter to stop them rather than help because they really want to invade our planet...
- It's stated it's not their entire planet that wants to invade, just some of it. Sending a bounty hunter is considerably less risky than sending soldiers who might reveal you.
- Memetic Mutation: "The Rock Driving" multi-panel exploitable.
- Special Effects Failure: The bullet scene.
- Took the Bad Film Seriously: Ciaran Hinds, who tries really hard to hold it together. (Ironic, given how much later he played Steppenwolf, a villain who was derided for not helping the movie hold together due to him not being much of a threat.]])
