No, it's not a teaser for a feature film, but a teaser for a video for an upcoming track titled Scare Me, directed by Brandon Dermer.
The single features Peaches and Timberlee, and is on the Major Lazer album, Free the Universe.
Major Lazer is the flying, laser-gunned fictional character created by DJs Diplo and Switch. It's also the name of their group.
