Other mistake: Taylor stated that when he arrived in terra Nova, it seemed like the blink of an eye for the people behind him, but he was alone for 118 days due to time dilation.

Other mistake: It is right after dinner when Angelina and Nick leave for the bar, but when they get there it's daytime.
