Is there an addon that makes sure the thx intro always plays before the movie?

This is the intro im talking about: http://www.youtube.com/watch?v=9pCw1sQOWRQ

There are many different THX intros that are cool. Is there a possibility to make XBMC play a random intro before every movie?

That would be amazing! Thank you

Try searching for the Cinima Experience addon. This will do that and much more.
