This UK version of the Guardians of the Galaxy trailer is certainly different than its American counterpart.
Whereas the US gets to see a lot of quips and light-hearted fun, the UK version is much more serious and follows more of the classic action movie tropes. Chris Pratt gives rousing speeches, Bradley Cooper mugs (albeit as a talking raccoon), and the tension and seemingly insurmountable odds are played up.
What it also gives us is a better sense of the plot, which is helpful given the relatively scant information coming from previous US trailers. Check it out above.
