Mike,
I know you mean the main feature but... consider this as well.
There are always things to do even after a movies release.
High quality shots of the characters (with alpha channels) for compositing.
Material for the press, coloring books, downloadable images for the kids. All that and more.
Of course the TWO wiki can always use a champion.
With TWO moving into final production there is a lot more to post on the wiki.
There's going to have to be credits at the end of the movie...
The making of...
I'm sure Martin has a lot more animation (refinement etc.) still to do too.
Send him an email and he'll find you something for you.
In many ways this is only the beginning.
Once word gets out about TWO people are going to want to see more.
You can provide the more!
