Did you read our collection rules ? Collections are only for true movie sequels. Animatrix doesn't meet this condition.

The Animatrix is a series of short animated films that happen within the matrix universe and have some of the same characters as the movies so they are officially part of the series of films

This will be a fit for our future planned universe type collections, but not with our current rules. Currently, the movies of a collection must be true movie sequels.

You can vote for this function.
