Some have criticized the stylings of the trailers for Thor Ragnarok for cashing in on the cult success that is being enjoyed by Marvel Studios other cosmic property Guardians of the Galaxy. While this is undoubtedly true on one level, it is also possible, in some small way, to be a reference to the TV movie The Incredible Hulk Returns. A continuation of the 1978-1982 TV series The Incredible Hulk which famously starred Bill Bixby and Lou Ferrigno as Dr. David Banner and the Incredible Hulk. Returns is the only other time in live action that the characters of Thor and Hulk have teamed up together separately of the Avengers. In Returns, Thor was portrayed by the American-Canadian actor Eric Allan Kramer (Robin Hood: Men in Tights) who played the character's arrogance for comedic effect, which Chris Hemsworth seems to be emulating. The TV movie was released in 1988, and the electric-synth stylings of the trailer seem's more in line with that period than the late seventies disco feel of the Guardians of the Galaxy.
It appears that, from what we see in the trailer, Benedict Cumberbatch's role as Doctor Strange in the movie will not be as one of 'the gang' that Thor assembles to take on Cate Blanchett's Goddess of Death Hela. This would be a shame as it would have been good for audiences to see three of the 'Best of British'; Tom Hiddleston, Idris Elba, and Cumberbatch share a scene together.
