The Flash movie has some pretty great music by Benjamin Wallfisch.  "Run" is one of the best tracks and is one of the best parts of the movie.  There are some other arrangements of this music out there, but they all are a little too advanced or nearly impossible to play, so I made this one that works better for my level.

I'm so glad Benjamin Wallfisch incorporated the 1989 Batman theme by Danny Elfman into The Flash score, because it goes hand in hand with Michael Keaton's version of Batman.  The theme appears multiple times in the movie, such as in "I Am Batman".
