The Martian (2015)
Unfortunately, as shown elsewhere and in the movie's advertising materials, surface operations start on November 8th, 2035, which makes Sol 18 at least the 25th of November, which is three days after Thanksgiving, and so all the potatoes should have been eaten. As Mark states when reviewing his food supply for the log, NASA sent up twice as much food 'for redundancy.' Logically they would have sent up twice as much of the thanksgiving food for the same reason. It does bring up the question of if they sent up an actual whole (and comparatively bulky) turkey or some other form, such as parts.

Errors in geography
The dust on Mars at the surface tends to be very fine, with grain sizes comparable to smoke particles. There are dust storms on Mars, but they look and behave like puffs of smoke instead of raging wind storms depicted in the movie.
Also, the astronauts would be able to lift heavy objects with less difficulty, since everything weighs less than half of what it weighs on Earth.
There are two major problems with this:
The suit value is around 4.7 PSI and 21% oxygen. That gives a "Partial Pressure" for oxygen of only around one PSI, which is not sufficient to support life - the minimum for survival is around 2 PSI, with nearer 3 PSI to allow normal levels of exertion.
4.7 PSI is a standard for NASA, but at that pressure almost pure oxygen is used.
By comparison, the HAB pressure are shown as around 12.5 - 14 PSI with 21% oxygen, giving around 2.5 - 3 PSI oxygen, roughly "earth atmosphere" range.
This gives the second problem - dropping from 12.5 or 14 PSI to 4.7 PSI pressure requires a progressive decompression sequence each time, which takes over two hours by the NASA protocol. The astronaut must pre-breathe pure oxygen to purge nitrogen from the body for this time, plus a period of "vigorous exercise" at the start of each pre-breathing and decompression sequence.
Without this, the astronaut will get "the bends" due to nitrogen in the body tissues forming bubbles.
The display is also in violation of the Code of Federal Regulations, 14 CFR 1221.113, "When the United States Flag and the NASA Flag are displayed on a speaker's platform in an auditorium, the United States Flag must occupy the position of honor and be placed at the speaker's right as the speaker faces the audience, with the NASA Flag at the speaker's left."
Vicodin is packaged as a solid pill (or caplet) and is not sold in capsule form.

Also, this repair is seen fluttering in the wind. Provided the seal would hold the entire 31.4 tons of pressure inside, it wouldn't flutter with that large inequality in pressure, no matter how strong the outside wind is.
They are using it to imitate the area around Pathfinder in order to decrypt the messages.
Listening closely reveals Sanders does in fact say 'Watney', though the last vowel sound is very quiet.
Keep in mind, we're not talking speeds measured in the Mbs range like your cell phone. These transmission rates would in the baud range, and as a radio transmission, may very well be received a character at a time.
