Craving more Guardians of the Galaxy after the trailer? That I cannot provide you, alas. What I can give you is the original music video for David Hasselhoff's "Hooked on a Feeling", which was prominently featured in the Guardians trailer.
This video is probably best watched while drunk. Enjoy the incredible cheesiness, truly remarkably bad CGI and cringe-inducing green screens. I honestly thought this thing came out in 1984 until I looked it up on Wikipedia and saw that Hasselhoff released this in 1999. OOGA CHAKA!
(Note - the version featured in the Guardians trailer is not actually David Hasselhoff's cover. The song was first performed in 1971, but the most famous version and the one used in the trailer is Blue Swede's 1974 cover. I do not, however, have an awesomely terrible cheesy music video to go with that version. OOGA CHAKA!)
