Fans have been waiting for Marvel and Lionsgate's Thor: Tales of Asgard feature since 2009, with only the occasional trailer and bits of concept art trickling out to give them more insights into the Thunder God's pre-Mjolnir years. Today IGN dropped the full skinny on the upcoming Blu-ray/DVD/digital download release, including its official drop date of May 17 (a timely 11 days after the release of the live action Thor film). Check out the animated feature's tentative list of extras after the jump.IGN runs down the extras:

-Audio commentary with Supervising Producer Craig Kyle and Screenwriter Greg Johnson

-Audio commentary with Supervising Director Gary Hartle, Animation Director Sam Liu and Character Designer Phil Bourassa

-"Worthy: The Making of Thor: Tales of Asgard" featurette

-The Avengers: Earth's Mightiest Heroes Bonus Episode from the new hit TV series

The feature's plot follows a young Thor (whose vest makes him look a little like Thunderstrike), his brother Loki and the Warriors Three on a quest for the Sword of Surthur. Unfortunately, their actions stir the Frost Giants, and the young heroes must claim responsibility by saving Asgard from attack.
