The DPA microphones recorded the dialogues of 'Guardians of the Galaxy' camouflaged

DPA's tiny lapel microphones allowed the Marvel production's head of sound, Simon Hayes, to capture the original dialogue on the set itself.

The Oscar winner and head of sound at Guardians of the Galaxy, Simon Hayes, relied on lapel microphones DPA to collect the dialogues in the Marvel film adaptation, directed by James Gunn.

Hayes, who first used DPA microphones in Oh mama (2008), he has relied on the DPA d:screet 4061 and 4071 miniature microphones in all the films he has worked on since then such as Les Miserables (for which Hayes collected the Oscar and the BAFTA for best sound mixing) and the next releases Tarzan, directed by David Yates and Kingsman: The Secret Service, directed by Matthew Vaughan.

Hayes chose the DPA miniatures for Guardians of the Galaxy since it allowed them to capture the original dialogue on the filming set itself. Director James Gunn wanted to preserve the authenticity and emotion of the actors' performance in this film.
The end result is that 75% of the film's dialogue was recorded with the DPA d:screet 4071s and DPA d:screet 4061.

To achieve this, Hayes actively collaborated with the makeup and effects departments to make the DPAs completely invisible on camera.
