A Facebook fan page has been started for Me and Orson Welles by a company representing CinemaNX. So if you are on FB support Zac and his castmates by becoming a fan!

They have also set up a youtube channel here.
Okay I lied, if I spent anytime on FB I probably would have noticed it faster, lol, but yes, the twitter @MeandOrson is linked from the FB page, thus seems legit too. So follow that too!
Also, FYI... I was asked to change the title on the YT Me and Orson Welles trailer we got off the 17 Again dvd to reflect that it is just a teaser trailer, specially made for Zac fans. I was also told that the actual trailer will be released soon and will feature more of the other cast, which is quite exciting! :)
ETA: There is a bebo page too :D http://www.bebo.com/Profile/meandorsonwelles
