Greta Gerwig's new $280 million Narnia movie is reportedly causing a stir within Netflix after some less-than-stellar test screenings over the summer.

'It's 100 percent true, and everyone at Netflix thinks the movie is awful. It's a genuine problem,' one source told entertainment journalist Jeff Sneider this week.

The film, titled Narnia: The Magician's Nephew, is the fourth solo outing from Academy Award-nominated director Greta Gerwig. She previously headed Barbie.

'The air went out of the room. It was bleak,' a second source said, describing the atmosphere in the theater once their viewing ended. Some previously unscheduled reshoots followed, according to Sneider.

The film features Meryl Streep as the voice of Aslan the lion, whom fans caught a glimpse of for the first time toward the end of the streamer's Led Zeppelin-laden trailer on Tuesday. 

Aslan is a male in the original seven-book series and is widely considered a literary representation of Jesus Christ. 

The casting doesn't necessarily mean that Aslan will be depicted as female but nonetheless has angered conservative critics.

The preview also featured a soundtrack from a band notorious for not granting the rights to use their music, Led Zeppelin.

Sneider's newsletter, The InSneider, reported last week that Gerwig, 43, recently complained to her agent about 'meddling' from Netflix executive Dan Lin, after receiving 'a lot of notes about early cuts' of the film.

Lin has been in charge of Netflix's film slate since 2024.

Another source told Sneider this week that the situation surrounding the upcoming film echoed a predicament that plagued Barbie during that film's post-production, where 'at least one individual - an experienced editor or director, or possibly both... was brought into the editing room to "save"' the film.   

The director's cut initially had Warner executives 'very worried,' according to Sneider, despite eventually being nominated for Best Picture. 

To substantiate the theory, Sneider cited how Narnia: The Magician's Nephew has three credited editors instead of Gerwig's usual one, with Wyatt Smith and Andrew Weisblum joining returning filmographer Nick Houy.

Sneider theorized that the increasing scale of Gerwig's projects could be her undoing. 

'I don't expect Gerwig to return for the Narnia sequel - if there is one,' he added, noting that while he enjoyed Tuesday's trailer, he 'trust[ed]' the review he received from the second source.

'I'd be curious to see how Narnia looks without one of the greatest songs of all time playing over the footage,' the report continued, referring to rock-opera ballad Stairway to Heaven, which band members Jimmy Page and Robert Plant famously refused all requests to license until this year.
