Oscar hosting is considered a primo gig, but it isn’t easy. The host needs to maintain the show’s energy, both for the audience inside the Dolby Theatre and for the millions of TV viewers. There is always a guessing game on hosts, but there are a limited number of individuals who have shown their talent in such a role. Ellen DeGeneres was successful at the March 2 rites, but apparently was reluctant even then to do it, and didn’t want to do it for the 2015 ceremony.
The March 2 ceremonies attracted the biggest Oscar viewership in 14 years, according to the Academy. It drew an average audience of 45.4 million total viewers, delivering a 13.7 rating among adults 18–49 (Live+7).Harris is currently co-starring in the current hit movie Gone Girl which may have a significant presence at the 2015 Oscars. He is the winner of 5 Oscars (3 for hosting various award ceremonies).
Maybe he will win one more for hosting the Oscars? Also, now all he is missing is the opportunity to host the Grammys and he will have achieved the EGOT of hosting.
