Continuity mistake: We see Shaw is on floor 7. However when he leaves, the outside of the building is only 4 stories high. (00:02:00)
Continuity mistake: When the Maserati does a slow cruise through the cemetery during the funeral, all the windows are tinted black. A few minutes later after Dom chases him and they crash head on into each other, the windows are no longer tinted.
Continuity mistake: In this film we find out that it was Deckard Shaw driving the car that crashes with Han. We then see Shaw drop Dom's cross in front of Han before the car explodes. However back in Tokyo Drift, we see all around the car before it explodes and Shaw is not seen. Given the footage from this film, he should have been visible in Tokyo Drift.
Continuity mistake: After the house explodes, Toretto is looking at it sideways in a close up. When the screen switches to an overview, he is standing right in front of the house looking forward. (00:17:15)
