10 More Glaring Plot Holes You Didn't Realise The Movie Actually Solved

10. Why Was There Gravity In The Dream's Third Level? - Inception

Almost automatically, because Inception is a Christopher Nolan film, there were elements and aspects that were confusing. Even after an explanation, things aren't always clear and it takes more than a few rewatches to understand fully, if at all.

One head-scratcher that the 2010 blockbuster presented had to do with gravity and how it affected each layer of the dream the crew were in. The first layer had them driving around in a van before heading into the second layer. When the vehicle drove off a bridge, the next level of the dream subsequently experienced no gravity. This is where the mindboggling fight scene with Joseph Gordon-Levitt jumping all over the hotel corridor walls came from.

However, in spite of level two experiencing no gravity, level three had no issues at all. Feet firmly planted on the ground. This has been taken as a plot hole, but it can be explained by one line from Tom Hardy's Eames.

Before the van hit freefall on level one, there was some rumbling felt on level two that Eames thought was too close to be turbulence from the reality of the plane, and so surmises it must be from the van driver in the previous level. The takeaway from this is that the effects of the upper levels get weaker the deeper they go into the dreams. So by this logic, being more than one level removed from the weightlessness in the van means they are far enough away that they don't feel it.
