From Contactmusic.com:
Superstar MATT DAMON will make a guest appearance as himself on animated U.S. T.V. show ARTHUR in September (07). In the episode, The Bourne Identity actor stops by Elwood City and chats to Arthur and his friends after they send him a script of their experiences he thinks will make a good television show. Damon's cameo appearance doubles as a promotion for his Project Greenlight screenwriting community, which strives to break budding writers in Hollywood.
We love it! Our little darlings won't be watching this episode alone. It's so nice to see an "A" list star have time for a bit of PBS Kids too!
This absolutely multiplies his hotness level.
Toodles.
