Here is Taylor Kitsch now, on the set of “Battleship” which is currently filming…

Dayam, the dude looks totally different with short hair and clean shaven!
Wonder if he’ll keep that short hair, now that he’s done filming “Friday Night Lights”? Probably not. I think he’ll grow the long hair back once he’s done with “Battleship”. He used to never believe in cutting his hair but I bet he was ordered to cut it for the “Battleship” role.
