Following the Blu-ray preview from yesterday, courtesy of James Gunn, we have two more excerpts from the Guardians of the Galaxy special features, with the director and his leading man Chris Pratt taking fans behind-the-scenes for a look at how the year's biggest blockbuster came together.

The first featurette showcases how important the music was on the set. The soundtrack has become a hit in its own right, topping the Billboard 200 charts shortly after its release. These songs, all hand-picked by the director, were important in setting the right tone during production. James Gunn explains how he wanted to contrast the dark setting of the opening scene with Star-Lord (Chris Pratt) dancing to Redbone's "Come and Get Your Love."

The second preview has Chris Pratt taking us through the epic dance battle that happens towards the end of this Marvel Phase Two adventure, which will be available on Blu-ray 3D, Blu-ray and DVD starting December 9.
