The chord progression for a part of the music in the trailers for both 47 Ronin (around :49) and 50 Shades of Grey (around 1:00) is the same. I recognize it from somewhere; does anyone know the origin of that chord progression?
47 Ronin uses Superhuman Kill the Fear by Def Con. Right at about 1:36 you can hear the chord progression used in the trailer at the point you specified.
50 shades of Grey uses Beyonce's Crazy Right Now. I won't link that, just because I won't. Both the music and the movie are not my cup of tea.
However, the chords sound different to me. I am not a musician and I cannot tell if either or both sampled someone else.
