The 2018 Oscars were a night to remember. From host Jimmy Kimmel's hilarious antics to poignant pleas for diversity in film, the award show will be the talk of the town.

Kimmel opened up the show with a powerful monologue that addressed the Time's Up and #MeToo movements, going in on Harvey Weinstein. "What happened with Harvey and what's happening all over is long overdue ... if we can work together to stop sexual harassment in the workplace. If we can do that, women will only have to deal with that every other place they go," he joked.

The host's opening monologue was far from the only time celebrities touched on the need for gender and racial diversity in film. Harvey Weinstein's victims united to plug Time's Up on stage, while Emma Stone called out the almost all-male best director nominees while presenting the award and Frances McDormand's acceptance speech had all the ladies (literally) on their feet.
