Sylvester Stallone takes his horse to the "Old Town Road" in the new Rambo movie! Rambo V: Last Blood comes out in September and it looks like Rambo is coming out of retirement and handling business again. Watch the newly released trailer and you'll hear a familiar song. Lil Nas X's "Old Town Road." Yes... the song that made the Country Charts only to be removed for "not being country enough" is now more than a viral sensation....it's in a RAMBO movie!
