Conversation at the Oscars last night centered on three films: Sam Mendes' 1917, Todd Phillips' Joker and Bong Joon-ho's Parasite. All three walked away with gongs, with Parasite the surprise big winner after picking up Best Picture, Best Director, Best International Picture and Best Original Screenplay. But another 2019 movie that earned no nominations also made some headlines: Alita: Battle Angel.
