Other mistake: When the Doctor tells the Atraxi "Oh, you're not the first lot to have come here, there have been so many," one of the monsters shown from their scan of Earth is a group of Ood. Even if in one of their uprisings they attacked the Earth, it would have been in the far future. The Doctor has had no encounters with them on Earth, and he knows them to be peaceful, so why would they be amongst the aliens who have threatened the planet? The only Ood who has been to Earth at this point is Ood Sigma, and he didn't come to attack. In addition, a group of Hath is also shown. These aliens have never been seen on Earth at all. (00:53:30)
Sam: Part 1 - S1-E7
Other mistake: When the Ranger first yells "SPD emergency," a piece of Jack's Morpher breaks off.
Other mistake: In the voice cast list, the Groom's Father appears twice - with two different voice actors - and the Groom's Mother is not even listed.
Other mistake: Laura is in the security control room of the plant, and finds a Master Lock Console screen; she sees it has Biometric Scan access and comments to Rich "It's not a retina scanner. It works on biometrics." She then brings up a photo ID of an employee on the monitor, lifts up the scanner and places it against the monitor, to get access. Firstly, retinal scans ARE biometric. She should have said "It's not an iris scanner," which requires a physical eyeball to scan. Secondly, no monitor from the 2005 period would be high-resolution enough to fool a biometric scanner.

Other mistake: The mayor and his crew have moustaches that defy any logic, still it should be noted that Van cuts them when they are extended for several feet but you see the cut and subsequent regrowth starting back from there a normal (for the average human) length.
