Other mistake: When Gabe and the bad guy are fighting on the helicopter on the side of the cliff look carefully at the rotor shaft - you can clearly see that it has changed. Earlier when it was on the ground you see the shaft and the scissors on it. When it is upside down the scissors have vanished and the rotor shaft has a different look to it.
Other mistake: When the two goofy base jumpers are seen camping out in their tent, they have a large lantern and a big cooler underneath the lantern. These items are quite bulky and fairly heavy, hardly the kind of stuff that extreme base jumpers would carry around in their packs. In fact, that stuff would be really hard to fit into their packs at all.
Other mistake: After the stalactite kills the man, Gabe lets him down. Notice how there's no blood on it.
Other mistake: In the beginning when Sylvester loses grip of the woman's hand, she falls to her death. Immediately after that they show the reaction of the helicopter pilot...and he's laughing.
Suggested correction: He's grimacing and shaking his head "no", not laughing.
Oh no... He's definitely smiling and laughing. It's unmistakable.
Other mistake: As Gabe (Sylvester Stallone) is being chased, he is seen stumbling and falling off several snowy terraces and hillsides. At one point, Gabe falls about ten feet, lands on a snowbed, and the entire snowbed literally "bounces" like a white, rubber pad.
Other mistake: When Walker shoots Travers on the ice, too much blood comes out on him in just one second.
