With The Dark Tower about to drop this friday, Gunslinger Idris Elba stopped by Jimmy Fallon for an interview. However, it wasn't long before Fallon pulled Idris Elba into one of his signature games, which found both participants rapping and singing along to hilariously inaccurate Google translated lyrics.
