I was watching FDTD 3 last night as part of the 4 feature blu-ray disc from Echo Bridge. It's missing an extra scene that appeared after the closing credits, on the disc it just stops at the end of the credits and NO EXTRA SCENE!
I know for a fact about the scene because it was on the DVD version form Dimension
hopefully Echo Bridge will do a repress with the scene intact, and offer a replacement program.
