Aliens are on the run on Guardians of the Galaxy's London set

Guardians of the Galaxy is currently filming in London, and the city's Millennium Bridge is serving as a venue for an alien escape. We get a look at what the movie's alien makeup looks like before any CG effects.

Hope72 posted photos from the set to her Tumblr, where you can see more of the images she nabbed and get a better look at the aliens and Nova Corps members hightailing it across the bridge.
