Factual error: Well into the movie, when the cop is searching Adrien Brody for contraband, the cop wouldn't be running his bare, ungloved fingers through Brody's mouth.
Continuity mistake: At the end, when Madeline is kicking dirt onto Harry when he is lying in the hole, the amount of dirt on his shirt changes from shot to shot.
Factual error: Liz is told by MILO that the planet they are heading for, Wolf 10-61c, has a permanent hot side and a permanent cold side due to its lack of rotation. Wrong. The planet circles its sun in 18 days. If it did not rotate, its sun would expose all sides of the planet to its rays every 18 days. In order to have permanent hot and cold sides, the rotation of the planet has to equal the 18 days around its sun. The same as the planet Mercury revolves and rotates at equal intervals around our Sun.
