Currently appearing on screen in “Bombshell”, Margot Robbie is already looking ahead to her next big-screen role as she marks the return of Harley Quinn.

The Aussie actress will lead a girl gang in the superhero movie “Birds of Prey: And the Fantabulous Emancipation of One Harley Quinn,” a spinoff of “Suicide Squad” Robbie conceived back in 2016.

Produced by Robbie’s Lucky Chap production company, “Birds Of Prey” features a lot of girl power on and off the screen.

Directed by Cathy Yan, written by Christina Hodson and produced by Robbie and Sue Kroll, the actress wanted to look into destructive relationships and schizophrenia in order to dive deeper into the character of Harley Quinn.

In an interview with Variety, Robbie says she “fell in love” with the character while embodying her in “Suicide Squad” but wanted to understand why a brilliant-yet-unstable woman would stay in a relationship with Joker who “wants to kill her most of the time.”

“Harley has this unpredictable nature that means she could react in any way to any situation, which as an actor is just a gift,” Robbie says, confirming Joker — neither Joaquin Phoenix’s nor Jared Leto’s take on the character – will appear in “Birds Of Prey”.

Though Robbie has high praise for Todd Phillips’ “Joker” and says Phoenix “did a phenomenal job,” “Birds Of Prey” will have a much different vibe.

“I feel like the ‘Joker’ film was much more grounded. Ours is different. It’s heightened,” she explains.

The project was greenlit before “Deadpool” was released and Robbie admits it took some “convincing” for the studio to get on board with an R-rated superhero film. Screenwriter Hodson agrees with Robbie’s vision for Harley.

“She really wanted to see Harley with girlfriends, Harley in a girl gang. Harley is such a naturally sociable character. And I think there was just a general longing to see girls together onscreen — women being friends,” Hodson adds.

Robbie also dishes on how she prepared for her role in “Bombshell”. It turns out, Robbie vehemently studied Elle Wood’s (Reese Witherspoon) monologue from a 2001 classic: “Every day, I’d do the monologue from ‘Legally Blonde’.”

“Birds of Prey” premieres Feb. 7.
