The Absolutely Fabulous star is set to host the 71st British Academy Film Awards for the first time.
She’s the first female host since Mariella Frostrup co-hosted with Stephen Fry back in 2001.
But the 71-year-old is asking everyone involved not to follow the precedent from this year’s Golden Globes and use the BAFTAs to make a stand.
At the 75th Golden Globe Awards, many people chose to wear black and #MeToo pins because of the accusations of sexual misconduct within Hollywood.
There is pressure for women attending the BAFTAs to also wear black – including the Duchess of Cambridge, who would break royal protocol if she did so.
“I’d so love it if not everybody used it as a platform for something else, because there are other times for those things”
But Joanna wants people to forget about politics for just one night and enjoy themselves.
Speaking to Good Morning Britain presenter Richard Arnold, Joanna made her point very clear.
She said: “I’d so love it if not everybody used it as a platform for something else, because there are other times for those things.
“This is the time to say, ‘Showbiz! Aren’t we so lucky to be in it?'”
Joanna explained: “I just want to celebrate the excellence of film, the sensational performances we’ve got this year.”
She added: “I just want people at home to love it, people who are coming up to get stuff to not be afraid, people are presenters to feel confident – it’ll be lovely.”
At last month’s Golden Globes, the biggest names in Hollywood – including Angelina Jolie, Penelope Cruz, Reese Witherspoon and Sarah Jessica Parker – wore all-black ensembles.
The Time’s Up movement was founded on January 1, 2018, by famous faces in Hollywood which has raised $ 20million (£14.4m) for a legal defence fund and gathered more than 200 volunteer lawyers.
It was set up to support working class women who have faced sexual harassment and assault at work.
It also pushes for legislation to punish companies which allow harassment to go on, and parity in studio and talent agencies.
The BAFTAs will take place on Sunday, so whether or not attendees also wear black in a nod to the movement is yet to be seen.
Good Morning Britain airs weekdays at 6am on ITV.
