desolation-of-smaug A first-time anonymous source informs that the Hobbit trailer will debut on Youtube on June 12.

Our anonymous tipster’s news seems to be reinforced by this story that popped up just a couple hours earlier on The Lebanese Cinema Movie Guide. The key part:

The first trailer from The Desolation Of Smaug, will be be attached to all of Man Of Steel prints. And it’s not a teaser trailer, but it’s a full 2 min 30 sec theatrical trailer. The trailer is set to debut online on June 12, 10 am PDT.

The eagle-eyed will note that the claimed 2 minute 30 seconds length conflicts with that listed in the approved listing on the British Board of Film Classification that we reported earlier today. So what gives? We don’t know, but for what it’s worth our source mentioned nothing except the date and the location.

UPDATE: We now hear that Alberta Film Classification has given the trailer a PG rating and has listed it with a running time of 2 minutes and 1 second. You can check it yourself here. Thanks to Ringer Jeremey for the heads-up!
