Dude’s right leg briefly bends backwards before it becomes his left leg and his right elbow is bent completely behind his back somehow after he hits the ice already. Edit: actually, i think his right hand disappears behind him and materializes out of his hood.

I wonder what the other 599 attempts looked like.

Edit: Ok, here’s the ad:

Here’s what else I found:

• Family in car: Girl in the back has no headrest.
• Rear shot of car: Wrapped gifts on the roof while it’s wet enough to warrant wipers. Presents aren’t secured by anything. Presents somehow bounce up off the rear of the car when it’s a hatchback.
• Guy on bakfiet (bike): pushes the right pedal straight down through the crank arm. Rear fork somehow bends like 45 degrees between the down tube and rear axle.
• Carolers: Despite the matching hats and jackets, dude in the front’s song book is twice the size of everyone else’s.
• Teddy bear: Teeth (gross). Woman on right wraps her hand around behind Teddy’s head, but that hand becomes woman on the left’s hand.
• Santa on sleigh: White car passes by in the background, but red car behind it somehow disappears. Maybe it somehow is driving on the sidewalk behind the parked car?
• Tree: Tree physically grows taller and larger when tie is cut. Fire in fireplace isn’t moving. Guy’s right arm briefly disappears. Actually, it looks like they might have manually spliced two takes here because there’s a weird slice around the man’s chest.
• Outside of the house: There’s apparently already a Christmas tree behind the family that you can see through the window. Also, the space with the bookshelf in the previous shot doesn’t exist here as the front door is right there.
• Sliding to a halt: The tracks in the snow left by the guy’s hand and armpits make no sense.
• Snowfall: cyclist to the right has a reflection, person behind them doesn’t. Cyclist randomly stops pedaling right at the end of the shot (maybe not, hard to tell).
• Ice ring: See above. Also dude middle-right stops and reverses without moving his feet.
• Falling from roof: Lights move and stretch weird, also house has two different styles of bay window. Also, looks like it might be a townhouse in which case, why is only one entrance fenced?
• Tram: Everyone in the tram is facing the camera. Nobody’s on their phone? There are a few frames where the door is 100% closed, but the woman’s feet are still standing on the inside floor of the tram instead of dropping to the pavement.
• Dining table: So much going on. Is that some kind of hibachi grill/fondue set in the foreground? I’d be more concerned about that catching fire. Nobody is reacting to the fire appropriately. What the hell is even on fire? Is that like burger patties on a grill?
• Cookies: Why are their crumbs everywhere if these cookies were presumably put in as dough. Also what the hell kind of cookies are they? Are they supposed to be gingerbread heads?
• Grandparents: Gramps got a stump for a hand the grows fingers. WTF card game are they playing?
• Up-close faces: Not much to say about these unless they’re supposed to be the old people from the previous shot, because they clearly aren’t.
• Bicycle spray: Cars parked on the sidewalk. Car passes through bicycle parked on the right which is also parked in the street.
• Baking: Girl has no reaction to explosion. Lots going on in the background. Is that orange juice being stored on an open shelf? Wine/martini glasses hanging upside down from nothing? Dude’s got some kind of industrial kitchen grade mixing device behind the girl and yet can’t operate a Kitchen-Aid?
• Cat in tree: What the hell are the people in the background doing? They start to take cover immediately. Drone changes from four arms with rotors to some kind of square shape with rotors at each corner after it hits the tree. Not sure what the thing falling off the left side of the tree is supposed to be.
• Tree lighting: Guy in the background reacts before anything happens. Girl on the left reacts despite looking at the floor/being asleep? Design of the table to the left changes when the lights go out. I wonder if this is another splice job where they needed to go through manually to make the lights-out synchronized. Also, why is this man plugging this in in the middle of the room anyway?
• Outdoor shot: Road layout has issues. Cars are driving right by cars parked the wrong way. Lamp posts are in the street. There’s a bizarre window jutting out of the roof across the street.
• McDonald’s entrance shots: I could be convinced these are real. The guy is the same person from the tree explosion who was probably comped in, so maybe it’s a real actor.
• Couple at McDonald’s: The girl kind of mimes drinking her drink. Guy in the background is clearly holding a mug
• Carolers again: There’s a weird fade with one of the building surfaces middle-left behind the carolers. This might be another manual comp (makes sense with the branding). Lamp behind them looks like a combination lamppost/sconce.
