What movies are like Final Fantasy Advent Children?

Any movie that comes under the action/fantasy genre will do.

A few films that i have seen and can think of that are similar are:

Final fantasy Spirits Within.

Ghost in the Shell.

Hellsing.

Beserk.

There are also spin off anime type OC's from the FF7 series:

Before Crisis (animation)

Crisis Core (animation)

Denziel's smile.

Alternatively play the conscending games to the Advent Children movie:

Crisis Core

Final Fantasy VII

Dirge Of Cerberus.

Hopefully that helps? =]
