Plot hole: The movie is based in 1986 after the group time travels from 2010. That makes it a 24 year trip back in time. It is stated that Jacob is 20 years old. That is an error as this would make him roughly around 23 or 24 if he was conceived in 1986, which we saw near the end of the movie.

Suggested correction: This mistake has already been corrected. Cusack could have simply generalized his age when he mentioned it, probably not remembering his real age at the moment.

Corrected entry: After being transported to the 1980s, the guys have possession of things which they did not take into the hot tub with them. Nick has his cell phone, Jacob has his snowboard, Lou has his backpack, and they are all wearing clothing that they brought with them when they go skiing.
Correction: This isn't a mistake, it's a plot point. They need the Russian energy drink to get back to the present.
I feel this is more of an excuse than a correction.

Factual error: When Phil is carving the ice sculpture, he slips and the chainsaw flies into the air, and it continues to run. Chainsaws will only run while you hold down the trigger.

Suggested correction: Easily rigged to be able to have the trigger held down without pushing on it.
