Unfortunately, it turns out that some Samsung laptops will fail to boot if too much of the [UEFI] variable storage space is used. We don't know what "too much" is yet, but writing a bunch of variables from Windows is enough to trigger it. I put some sample code here — it writes out 36 variables each containing a kilobyte of random data. I ran this as an administrator under Windows and then rebooted the system. It never came back.

Among the people who appear in the trailer are Linus Torvalds, Bradley Kuhn, Greg Kroah-Hartman and others. A special case is RMS who can't be interviewed "because he is too demanding" (according to a comment by Keith Curtis, the author of the movie, posted at the trailer youtube page)."
