After a topsy-turvy Oscar season in which frontrunners were constantly shuffled, old tweets hobbled a top contender and space was held for “Wicked,” the 97th Academy Awards get underway Sunday. Sunday’s Academy Awards, at the Dolby Theatre in Los Angeles, will bring to a close one of the most unpredictable Oscar races in recent memory. The ceremony kicks off 7 p.m. EST and will be broadcast by ABC and streamed on Hulu. Conan O’Brien is hosting for the first time.
