Figure skating will surely be one of the most-anticipated events at the Sochi Olympics. But in Hollywood, filmmakers have taken a few liberties on the ice, namely when it comes to some of the technical elements. And the judges are not impressed.
The Cutting Edge
It's a climactic moment near the end of the 1992 movie, The Cutting Edge, when figure skater Kate Moseley (played by actress Moira Kelly) turns to her pairs partner Doug Dorsey (D.B. Sweeney) just before they are to take the ice at the Olympics and excitedly declares, “we're doing the Pamchenko!”
Frantic, Doug tries to talk her out of it. “Forget it. It's too dangerous,” he yells over the sound of the cheering crowd at the skating arena.
They argue up to the very moment their music starts on the ice about whether to attempt the controversial “Pamchenko twist,” a highly difficult and dangerous maneuver their coach invented that, if completed during their skate, would mean an instant gold medal. Long story short (spoiler), they execute the move flawlessly and the movie ends with no doubt that they've won Olympic gold.
It's a triumphant ending. But let's just say there's a very good reason the filmmakers used a series of cuts to create the illusion that they actually did the move. The truth is, the Pamchenko twist is impossible.
Earlier in the film, coach Anton Pamchenko (Roy Dotrice) tosses a bunch of weathered looking diagrams on the ice during a practice that detail a highly dangerous pairs move he has been inventing for the last 20 years.
Intrigued, Doug takes a look. “A bounce spin into a throw twist ... and I catch her?”
The Pamchenko twist does have a basis in reality. It is composed of two parts, as Doug deftly put it. The first part is a “bounce spin,” which is a real move that is actually illegal in competition, per International Skating Union rules. It's often performed in exhibitions and shows because it is quite a death-defying crowd pleaser—the man grabs the woman by the her feet and swings her up and down as he rotates. The woman's head typically comes mere inches from smashing on the ice if it is done correctly. If done incorrectly ...well just try not to think about that.
The second part is a “throw twist,” more commonly known as a “split twist.” This is a required technical element in high-level pairs competition. To get full credit, a man and woman must start skating backward together. The male partner typically launches the female above his head, where she splits her legs and twists in midair as she pulls them back together. The man catches her as she comes down. Elite-level pairs teams regularly complete triple-twists (the woman does three rotations in the air). Two-time Olympic champions Ekaterina Gordeeva and Sergei Grinkov completed a textbook split triple-twist in their long program in the 1988 Olympics—the first technical element in this video.
Now, put the bounce spin together with the throw twist. The physics just don't compute. The centrifugal force built up during the bounce spin would launch the woman—assuming she is released at the highest point of the bounce spin—on a parabolic trajectory. In theory, she could use the momentum to twist in the air, but it's highly unlikely that she would thrown high enough to pull it off without getting her head smashed on the ice during the bounce spin. And even if she did, the horizontal trajectory would launch her so far away from her partner that there's no realistic way he could have enough time to stop his own momentum from the spinning and traverse the distance to catch her.
Pamchenko says in the film that it's all about the timing. But frankly, it's not worth risking the horrifying injuries that would inevitably result to test his theory. There are plenty of other legal and physically possible moves pairs skaters can spend their time and energy perfecting.
Blades of Glory
The Iron Lotus from Blades of Glory is not one of those moves.
In that film, Will Ferrell and Jon Heder play two champion singles skaters who are banned from men's competition for life after an unseemly incident at a competition. Desperate to get back on the ice, they team up as a pair. In order to stand a chance of beating reigning pairs champions Stronz and Fairchild (Amy Poehler and Will Arnett), they attempt a highly dangerous and difficult maneuver called the Iron Lotus—which has only ever been attempted in North Korea with comically disastrous results.
If the Pamchenko Twist is impossible, the Iron Lotus is downright laughable—which is the point, of course. It starts out the same way, with a bounce spin. However, at the height of the bounce, the male skater launches the female into a back flip instead of a twist. While she's flipping, he does an arabian cartwheel underneath her. Once completed, he catches her by the arm and leg, and the pair gracefully rotate out of it together.
“I swear to God, if you cut my head off,” Chazz Michael Michaels (Ferrell) warns his partner, Jimmy MacElroy (Heder), before they attempt it in the final performance of the film. As they launch into it, their coach (Craig T. Nelson) screams, “No! Don't do it! I was wrong, it's suicide!”
But wordlessly, magically, they nail it. Or rather, computer-animated stunt doubles nail it, because it's physically impossible. It would require the “female” skater to reverse her momentum in mid-air to transition from the bounce spin into the back flip. Maybe it's possible on the moon, where gravity isn't so much of a factor.
So what have we learned from this little figure skating physics lesson? You won't be seeing any Pamchenko Twists or Iron Lotuses in Sochi. And don't try any of this at home.
