When the world's most famous rock climber, Alex Honnold of Free Solo fame, says that your movie has “probably the worst scene in all of climbing,” it is safe to say your film isn’t a great depiction of the sport it displays. Vertical Limit has some pretty intense scenes featuring some scary rock-climbing moments, but it is plain as day how the characters' choices are removed from reality and the physics of real climbing vs. what happens on-screen.
In the GQ interview where Honnold breaks down the most infamous scene from the movie when a character cuts the rope holding their father, sending him to his demise, he points out several factors that make the scene complete and utter fiction. In the scene, five climbers attached to the same rope lose their grips and are suspended in midair. After they’re suspended, the mechanism holding them begins to falter. Honnold points out that if they were to all fall as they do but are initially caught and held up by the mechanism, then there is no way it would suddenly lose its grip.
If they were going to fall to their deaths, it would have been when the initial fall occurred, not when dramatically holding on for dear life afterward. Secondly, he points out that no sandstone structures in the world have an overhang as the wall does in the film. If this were real, they would have been right up against the wall after their initial fall, able to get a grip and not suspended several feet in the air away from it. Lastly, he points out the rather obvious that at no point in the real world would you ever intentionally cut the rope that's keeping someone alive, especially not if they are your father.
