At first I thought this might be a joke, but apparently it's not.
I wish the title of the video didn't mention the movie they're making, because I definitely wouldn't have thought that these three men would actually be making a movie version of Jem and the Holograms!
The script "centers on an orphaned teenage girl who becomes an online recording sensation. She and her sisters embark on a music-driven scavenger hunt - one that sends them on an adventure across Los Angeles in an attempt to unlock a final message left by her father." I'm assuming that's just the first 30 minutes of the movie, but I could be wrong.
