While chatting on Monday’s episode of Marc Maron’sWTFpodcast, the 58-year-old director opened up about howJennifer Lawrencewas originally considered for the role ofCharles Mansoncult member Squeaky Fromme, a part that would later go toDakota Fanning.

“She read it, and afterward, we talked about it a little bit. She was interested in doing it, but something didn’t work out,” Tarantino continued, adding that Lawrence, 30, is “a very nice person, and I respect her as an actress.”

Of Fanning, 27, who would later be cast in the role, thePulp Fictionhelmer also said, “I couldn’t be happier with what Dakota Fanning did; it’s one of the best performances in the movie. I think she’s amazing as Squeaky Fromme. She becomes [her].”

Earlier this month, Tarantino opened up about how he is standing firm in his decision toretire from filmmakingdespite being one of Hollywood’s most celebrated directors working today.

Appearing on thePure Cinema Podcast(viaMovieMaker), the filmmaker discussed his imminent retirement and trying to avoid the possibility of ending his career on a bad movie.

“Most directors have horrible last movies,” Tarantino said. “Usually their worst movies are their last movies. That’s the case for most of the Golden Age directors that ended up making their last movies in the late ’60s and the ’70s, then that ended up being the case for most of the New Hollywood directors who made their last movies in the late ’80s and the ’90s.”

TheDjango UnchainedOscar winner referenced Arthur Penn’sBonnie & Clydeas an example of this pattern, saying, “I’m not a super huge fan of this director, but the fact that Arthur Penn’s last movie isPenn & Teller Get Killedis a metaphor for how crummy most of the New Hollywood directors' last, last films were. So to actually end your career on a decent movie is rare. To end it with, like, a good movie is kind of phenomenal.”

“I mean, most directors' last films are f—ing lousy,” he added. “Maybe Ishould not make another moviebecause I could be really happy with dropping the mic.”

Once Upon a Time in Hollywood, which scored 10 nominations at the 92ndAcademy Awards, was Tarantino’s ninth film.

And while the director has previously stated he would cap his career at 10 movies,he joked about calling it quitsearly if the 2019 film was “really well-received” prior to its release.

“I see myself writing books and starting to write theatre, so I’ll still be creative,” Tarantino toldGQ Australia. (He has sinceembarked on the book journey.) “I just think I’ve given all I have to give to movies.”
