We've probably been remiss in not putting Alejandro González Iñárritu on the Creativity 50 until now. The accomplished director, repped by Anonymous Content, has cemented his reputation in advertising with brilliant ads such as Nike's Cannes Lions Grand Prix-winning "Write the Future" and P&G's Emmy-winning "Best Job." There's also his illustrious features oeuvre, which includes such acclaimed films as "21 Grams," "Babel," "Biutiful" and "Amores Perros." But in 2015, he reached a career high with "Birdman." Starring Michael Keaton, the movie followed a washed-up actor trying to reclaim his creative reputation with an ambitious Broadway production -- and went on to win four major Academy Awards: Best Director, Best Picture, Best Original Screenplay and Best Cinematography. Mr. Iñárritu continues to excite Hollywood with his upcoming film "Revenant," which critics are already pegging as a big contender at next year's Oscars.
