Jurassic World, Avengers, Ant Man, Straight Outta Compton and some flops (Tomorrowland, Terminator) will get mentions. I could see them doing Inside Out as well since they did a similar gag last year. Star Wars probably as well
As for real life people, I mean... Trump. Period. That's going to be the whole show. Jared from Subway I can see getting massacred. I don't know if they'll come close to touching Jenner. That's almost as touchy as gun issues.
If SNL writers are involved I do wonder if that means that Avatarland bit won't be present. It'd be a shame.
