Thor: The Dark World - Trailer

Based on all of the trailers for Iron Man 3 and this new Thor trailer, the Marvel series is taking a darker turn it appears. And it looks like Loki is back in the picture for a 3rd time. His character has been a little weak, but based on this clip he may be changing from his bad side to help his brother. Probably just another trick. We'll have to see. Either way...keep these movies coming Marvel!
