Watch Jimmy Kimmel's opening monologue

Los Angeles - Host Jimmy Kimmel opened the 90th Academy Awards with a monologue that mixed Weinstein punchlines with earnest comments about reforming gender equality in Hollywood. 

And of course, Kimmel — returning to the scene of the flub — dove straight into material about last year's infamous best-picture mix-up.

"I do want to mention, this year, when you hear your name called, don't get up right away," said Kimmel. "Give us a minute."

But while Kimmel spent a few moments on the fiasco known as Envelopegate, he expended far more minutes frankly and soberly discussing the parade of sexual harassment allegations in the wake of the revelations regarding Weinstein. Kimmel cited the industry's poor record for female directors and equal pay.

"We can't let bad behaviour slide anymore," said Kimmel. "The world is watching us."

Gesturing to a giant statue on the stage, he praised Oscar, himself for keeping "his hands where you can see them" and for having "no penis at all." But Kimmel introduced the broadcast as "a night for positivity," and cited, among other things, the box-office success of Black Panther and Wonder Woman.

"I remember a time when the major studios didn't believe a woman or a minority could open a superhero movie — and the reason I remember that time is because it was March of last year," said Kimmel.
