Guardians Cast Their... Yondu?

In a semi-strange casting reveal, Marvel has cast Michael Rooker as Yondu. Rooker has worked with Guardians' helm James Gunn before (Slither & Super) and he "just" finished his stint on Walked Dead as racist, one-handed badass Merle. He's a damn good actor and I'm definitely on board with him joining the cast. The odd thing is that it's as original Guardian Yondu when the current roster and movie are suppose to be based on the latest team/book from the brilliant DnA run (the original also being from the future). My initial assumtion is that with Rooker being a bit older, it's a part that is showing the "history" of the team and not necessarily an active member of the team. Either way, I'm intrigued with the casting and look forward to seeing how he fits in.
