Ashe: Do you know what they call a gathering of crows, Curve? A murder. A murder of crows. Think about it.
Throughout the movie, we can hear Ash's motorcycle shift gears, but we can see that his hands never disengage the clutch, a must do for a smooth shift like we hear.
The first piece of graffiti Ashe runs past when he returns to his work shop says "Wings", kind of fitting given his resurrection was due to a Crow. Also Sarah has wings tattooed on her back.
