Continuity mistake: Vic offers to take Sue's things to one of his condos. While he says "You'll have 'round the clock care'" he is holding dark-colored pants.

Continuity mistake: When Mr. Fantastic is writing a problem on his chalkboard, right before the camera switches to Von Doom picking at his scar, you can see that Mr. Fantastic already wrote 4= Sxlo -4 and underlined it.

Suggested correction: He kicks away the stony skin that covered his body before. It simply detached.

Continuity mistake: When Ben squashes the bag of oranges to make juice, none of them are actually squashed.
Factual error: When Reed and Sue are testing the Human Torch's powers, they claim that a temperature as high as the Human Torch's (5000 K to 6000 K) will "ignite the atmosphere and destroy all life". This is incorrect. Many experiments in the lab and on the field have produced temperatures several orders of magnitude larger than the temperature of the Human Torch on a similar scale. Nuclear explosions can generate temperatures in excess of 8000000 K, and temperatures produced by the largest X-ray generator (the Z machine) have been as high as 3700000000 K. Such tests have not ignited the atmosphere.
Other mistake: Julian McMahon's real Australian accent slips through when his assistant asks him if he should rest and McMahon says, "Later. First I have some unfinished business to attend to."
Continuity mistake: Sue's picture on the magazine cover and on the TV report has her eyes brown.
