well as long as this is for fun, I'm going to say Rami Malek will win best leading actor, he has the golden globe, he has the SAG award, the oscar is essentially his to lose (besides I saw BR twice, loved the hell out of it, definitely worth the wait and the 5+ years in development hell. Yes I noticed the inaccuracies, but they didn't bother me)
and just to be random I'm going to say Spiderman into the Spiderverse will probably win best animated feature, I haven't seen it, but I was disappointed with Ralph Breaks the Internet, I enjoyed Incredibles 2 very much, especially since it has really been the only Pixar sequel I ever really wanted (and this is saying much since I'm not much of a Superhero film person despite seeing all four reeve era films) but this would be great for Sony Pictures Animation if they win (besides it's not often a studio other than Disney wins in that category)
Animated Short: Bao, next!
Best Song: I know it's probably going to go to Shallow from A Star is Born, but if you heard the nominated song from Mary Poppins Returns you will kind of tear up...it's just a shame that they won't bother with Best Song performances at the oscars this year but then again Trip a Little Light Fantastic isn't nominated and that would have been cool to see on stage. I really, really, really wish that Queen would release an unreleased song and put it in Bohemian Rhapsody just to qualify for this category, but we can't all get what we want.
