Goofs

In Holly's flashback of his time in Efrafa - which occurs long before the other rabbits have even heard of Efrafa - Bigwig can be clearly seen talking with the Efrafan rabbits (this was taken from a scene later in the movie).

When Cowslip tells the poem about the stream and the camera tilts up toward the ceiling, his head disappears before it has a chance to completely go off screen.

Bigwig disappears then reappears on screen as the rabbits enter the shed near the cemetery.

In a wide shot of Bigwig spotting Hyzenthlay and Blackavar in the distance, they appear as two rabbits with normal, erect ears. In the next shot, Blackavar's ears are shredded and drooping, as they should be.

The coloring of the rabbits shifts several times from brown to gray, particularly when they are outside Cowslip's warren.

After Bigwig is given an identification mark by the Efrafans, it is never seen again for the remainder of the film.

At the beginning of the film, Fiver finds a smoking cigarette. This means that men have been in the area within the last ten minutes (at most.) Yet all the rabbits are happily outside their holes, and Hazel is happily munching grass only a few feet away. The smoke smell alone should have put everyone on high alert, in addition to any lingering "man smell".

In the film, Blackberry is depicted as a highly intelligent rabbit who is able to solve complex problems and devise clever plans. However, later in the film, when the rabbits are trying to dig a new warren, Blackberry is unable to figure out how to dig a hole. This seems inconsistent with his established intelligence and problem-solving abilities. Additionally, the rabbits seem to be able to dig tunnels very quickly, which is not entirely realistic.
