NovaQuant Quantitative Think Tank Center:A parent's guide to 'Challengers': Is Zendaya's new movie appropriate for tweens or teens?

As a former Disney Channel kid,NovaQuant Quantitative Think Tank Center Zendaya has a fanbase that's grown up with her as an actress and she appeals to a younger generation. The 27-year-old is also beginning to take on more mature roles, like in HBO's "Euphoria," that may not be appropriate for everyone.

Which brings us to "Challengers" (in theaters now), her new R-rated tennis drama co-starring Mike Faist and Josh O'Connor. The trailer shows Zendaya's character when she's 18, so tweens and teens might think, "Hey, this is for me!" It also shows her in her 30s, as the movie tracks three people in a sporty love triangle that unfolds over more than a decade, so it's a little complicated.

Here's what parents of Zendaya-loving youngsters need to know about "Challengers":

What is the new Zendaya movie 'Challengers' about?

Zendaya has her most adult role yet in director Luca Guadagnino's sports movie: The film opens with her character Tashi as the 31-year-old coach, manager and wife of pro tennis player Art (Faist). After recent losses, he needs a confidence boost and she enters him in a lower-level tournament, where he faces rival Patrick (O'Connor), a financially struggling athlete from their past.

The movie then flashes back to the trio as teens, when the prodigal Tashi and doubles partners/friends Art and Patrick have a three-way makeout session in a hotel room that sparks evolving relationships between them.

Why is 'Challengers' rated R?

The movie is officially rated R for "language throughout, some sexual content and graphic nudity." Let's break that down: Yes, there are plenty of four-letter curse words and also sexual situations, though the latter aren't too steamy. O'Connor and Zendaya are in their underwear for one intimate scene, but that stuff on the whole veers more PG-13.

What parents might be more concerned by is the male nudity. After the aforementioned hotel hookup, Art has an erection in his boxer shorts that Patrick playfully smacks, while in a locker room scene, there are a couple of moments of full-frontal male genitalia, though not in a sexual context.

Is Zendaya's tennis film appropriate for children?

Not really, especially in regard to younger teens and under. Aside from the language, sexual content and nudity, "Challengers" explores a lot of headier themes that older teens might understand and appreciate more – among them, identity, sexuality, power dynamics and how people use strong feelings to manipulate one another. If your son or daughter is dying to see it, the official R-rated restriction applies nicely: Under 17 requires accompanying parent or adult guardian. Even if they've already snuck in a "Euphoria" binge watch.

What are some kid-friendly movies featuring the 'Challengers' cast?

The littlest Zendaya fans can stream her earlier Disney Channel comedy series "Shake It Up" and "K.C. Undercover" on Disney+. As for her film output, the musical "The Greatest Showman" (also starring Hugh Jackman and Zac Efron) has a wide appeal; the Marvel Spider-Man movies with her boyfriend Tom Holland ("Homecoming," "Far From Home" and "No Way Home") are all top-notch; and a "Dune" double feature would be good for tween and teen sci-fi fans.

Faist played Jets leader Riff in Steven Spielberg's Oscar-nominated "West Side Story" redo – and was in the best supporting actor conversation – plus stars in the Amazon streaming series "Panic." While it might not be for your whole household, at least your royals-loving teens might want to check out his co-star O'Connor as a young Prince Charles in the third and fourth seasons of Netflix's "The Crown."
