This new featurette from Alan Taylor’s Thor: The Dark World focuses on the always strained fraternal relationship between Thor and Loki.  The scenes in which Thor attempts to recruit Loki to help in the fight against Malekith and his hordes have been seen in previous trailers, but there’s plenty of new footage here as well as interesting interview clips with Tom Hiddleston (Loki) and Chris Hemsworth (Thor).
 
With Thor: The Dark World debuting overseas on October 30th and nationwide on November 8th, the pace of publicity has picked up.  Earlier this week Marvel Studios released a photo of actor Chris O’Dowd, whose role in the film is still unknown (see "First Shot of Chris O'Dowd in 'Thor: The Dark World'" and "New Malekith Poster and 'Thor' TV Spot").
