Question about the Nightcrawler goof in X2

Was it intentional?



We don't know how his powers truly work in the movie universe... maybe an "imago" is formed wherever he is going to teleport?



I'm talking about the fact you see his "shadow" in the cage of the kids before he would teleport into it...



Anyway, his "shape" is barely noticeable, and they could digitally remove that in future blu-ray releases.
