Actually, I have a solution for you on this....an accidental one, but a solution none the less.
In iTunes, because back in version whichever, you could only have a certain number of playlists, that when they brought in folders, I grouped my playlists into two main folders...Movies, and Music. Within them I then placed appropriate playlists. By Actors, Years, special groupings that meant something to my wife

)...like Chick Flicks) etc
Since I got my atv2, Ive noticed that the folder itself is classed as a playlist and shows ALL the movies within the playlists inside it.
So, if you create a Folder for 2010 movies, manually drop them into it, then create smart playlists or whatever WITHIN that folder, you'll end with a main list of 2010 movies, PLUS the sub divisions your after.
I say this because this is how mines working at the moment. Of course, if they ever fix atv2 to behave like atv1, this will need adjusting to your needs.
Play around with the folder/playlist stuff in iTunes. I have in my Movies folder a Stars folder which contains smart playlists based on actors, smart playlists based on year of release and many more.
Its a quick and easy play to adjust this setup and you can check your results on your atv2 at will.
