Well it was definitely about to topple early on, when we first see Cobb walk away from the table (because that was clearly a real spin done in-camera), but I never saw it wobble HALF as bad as that when we cut back to the table again. And I was watching pretty damn intently.
Unless you guys all saw a different print from me.
At the very least, we have to accept that Nolan wanted the scene to be read both ways.
Exactly as I saw it. No wobbling suggesting a topple at the cut. What would it matter if it did wobble anyway? It's explicitly explained in the film that it has to topple or it's a dream. It doesn't topple. Saying it probably toppled after the cut is no more helpful than me pointing out it could wobble for 60 years and still not topple in a dream.
It's actually silly that Cobb would even walk away from it before it topples. Given all he's been through and all the questioning of what's reality, especially surrounding his wife's death, you'd think he'd make sure ... probably long before getting home.
Why couldn't the kids just be flown to live with Cobb overseas?
