Factual error: Writer/director Adam MacDonald boasted that he studied black bear predatory behavior and black bear attacks on humans for years in preparation for making this film, because he wanted to depict a black bear attack in as factual and as authentic a manner as possible. But, at the most crucial point in this film (when the black bear actually does attack Alex and Jenn), factual accuracy goes out the window. As Alex and Jenn cower in terror, the bear lunges into their tent and bites into Alex's leg; whereupon, Jenn fires a can of bear spray (a stifling pepper-based chemical) point-blank into the animal's face. The startled bear retreats for a moment, but then lunges into the tent again, dragging Alex outside and killing him; thereafter, the bear continues pursuing Jenn for the remainder of the film. However, according to years of extensive study by the University of Calgary, no bear has ever attacked a human after the animal was sprayed with bear spray, much less resumed an attack, as depicted in this film. To date, the success rate of defensive bear spray is 100%. So, the factual accuracy of "Backcountry" was abandoned for the sake of cheap thrills.
Factual error: The film makes use of a real Broadway theater, the St. James, which is on West 44th St. When they leave the stage door, the actors are next to the Edison Hotel, which is on 47th St.
Character mistake: Nikki lost her insulin kit and needs insulin. Her mother suggests getting her a fruit juice, something sweet. Fruit juice contains a large amount of sugar which raises blood sugar levels very quickly. Therefore, people with diabetes are usually best to avoid drinking fruit juice. Her suggestion is absurd.
Audio problem: When Dawson and Amanda are at the Vandemere House, there is a nighttime scene where they are in the living room. Dawson is by the fire, and Amanda is on the couch. You can see Amanda's profile, and you hear her say something about turning on the radio last time they were there, and how she knew a song would come on. And you hear her laughing, but her lips and chin do not move. (01:18:00)
Continuity mistake: When they come over the mountain, Moses looks out at the Red Sea and sees nothing on the horizon. When they get across, they can see the mountains where they crossed very easily - the area on other side has mountains similar to the ones they crossed, which should have been visible when first approaching.
Character mistake: When the supply convoy is ambushed, Soto is instructed to get on the .50 caliber. However, the weapon on the gun ring is a .30 caliber M1919 machine gun, not a "Ma Deuce" .50 caliber.
Continuity mistake: When Anna Kendrick visits Jennifer Aniston in the hospital it shows a cake from different views. When the views change the candles light and relight. (01:14:30 - 01:15:25)
Suggested correction: The candles on the cake never light and relight. They are always lit from the point when Anna Kendrick (Nina) lights them. In one shot they look unlit due to the pillow behind them but if you look closely they are always lit.
Character mistake: At the hospital, Alice's husband says, "Here we are, in a major hospital, and they only have one elevator." In fact, there are two elevators, right beside each other. He actually looks at the other one before making the comment.
Suggested correction: He meant one elevator bank that actually worked. During the time they waited, none came.
Exactly. He says "they only have one elevator running", which is different than saying they only had one elevator.
Continuity mistake: The appearance/structure of the ground-level components of the well changes several times. In the first view, the unit is mostly gray and rusty with one vertical white pipe. When Ernest is pumping, half of the horizontal pipe is also white and clean. In the rear view, the vertical pipe is brown and rusty. Some mud spurts out of the spigot, but the spigot is clean, dry, and white in the front view. (00:05:10)
Continuity mistake: The glass that was dropped and shattered on the floor had a different pattern of fragments when Mitch [Robin Williams] knelt to clean it up. Most obvious was that the majority of shattered pieces settled toward Mitch's feet but were on the opposite side of the largest piece of glass during clean-up. There's also a "stupidity" in the way Mitch wiped up the glass - pressing down on the thin towel (apparently to entrap fragments), which is most likely to result in getting pierced. (00:01:40)
Factual error: While Evans and Eve are still in Grand Central they overhear an announcement which states "According to Port Authority policy This station will be closing for the evening." Grand Central is not part of the NY/NJ Port Authority. Also Grand Central is a terminal, not a station, as trains do not pass through Grand Central, they enter and turn around.
Character mistake: At the end of the movie, when Jaggu is listening to the sounds recorded by PK, the audio contains the question which she asked, "Tumhare planet pe sab aise hi hote, bade kan wale?" but does not contain the answer which PK gave, even though he was sitting right there. This seems to suggest that PK did not exist in the real world.
Character mistake: Mitch states that he is Pisces then goes on to state that his birthday is 25th of March. The Pisces period goes from 19th February to 20th of March. Mitch would actually be Aries. (00:35:00 - 00:37:00)
Revealing mistake: JR is in the weapon container of the crazy dealer, who passes him some of his goods. JR ends up holding in his right arm a MP5K and an M4A1, which combined are about 5 kilos, but then he passes him an M60 Machine Gun, which weighs over 10 kilos and that the relatively diminutive protagonist just handles throughout the scene gripping it with his left hand and making no effort whatsoever. (00:25:20)
Continuity mistake: During the scene of the first meeting between Gus and Ruby, Krysten Ritter's hair moves back and forth (behind or in front of her left shoulder) between shots multiple times (most obvious example: when he offers her a drink). (00:12:45 - 00:14:35)
Factual error: In a classroom scene, Mia takes her phone out and checks Instagram. It can be seen that she is on the network "Koodo" - a Canadian mobile operator. The movie takes place in Portland, but is filmed in Vancouver. (01:00:10)
Continuity mistake: In the beginning, Schapelle checks the boogie bag in in the check-in counter. Then she's seen carrying it over her shoulder. Then a baggage handler takes it away from the check-in counter.
Factual error: The "Italian" police wear obvious fake uniforms, they're US style.
Factual error: The three panzers that ambushed the Hellcats are supposed to be Mk. III's with the 50mm gun, but they only had 5 bogie wheels, instead of 6, and no driver or radio operator's hatches.
Continuity mistake: When Kat first visits the detective, she sits on the couch and drinks beer. Behind her is a table with a lamp and a green bottle of beer. In the next scene the bottle disappears, and reappears in the next scene. (00:34:00 - 00:35:00)
