Why would there need to be? It doesn’t sound like there was any studio interference or that the film makers were unhappy with the final cut.

I didn’t know about this:

Sean Bobbitt served as cinematographer, who preferred using handheld cameras and natural lighting. Cianfrance saw Bobbitt’s experience as a war photographer as an advantage, and was impressed with his process and sense of composition, which proved useful for a scene in the beginning which featured a tracking shot towards the globe of death. Bobbitt initially stood inside the globe to capture footage of the motorcyclists, but a bike hit his head and he suffered a concussion. As a result, the director did not allow him inside again.
