Come on, Clooney is and has been box office poison for YEARS. Other than Oceans 11 and it's sequals, what has he actually been in that has made any money whatsoever? Nothing except an indie film here and there that made modest returns ("Up in the Air") and cameos in movies that did make money but not because of him ("Gravity").
His big ticket pictures have all bombed. "The American", "Money Monster", "Syriana", "Tomorrowland", "Hail, Caesar", "Leatherheads" etc. All BOMBS!
It’s rumored that Clooney likes to hit the “sauce” frequently.
