Soldado Director Stefano Sollima Will Not Return For 'Sicario 3' - This is good news. Word is Sollima changed the 3rd act of Sicario 2 and it wasn't for the better. Sheridan's script would have never had the ending "So, you want to be a Sicario?" Shitty ending to a great movie. That sounds like a line written by a kid that wants to be a screenwriter.
