Enola Holmes may have only landed on Netflix on Wednesday, but it looks like it’s already shaping up to be a huge hit.

Based on the book series by Nancy Springer, the film stars Stranger Things’ Millie Bobby Brown as Sherlock Holmes’ teenaged sister Enola, and follows her as she heads to London to investigate her mother’s disappearance, only to end up drawn into another mystery involving a runaway lord.

Alongside Brown, the film also stars Henry Cavill, Helena Bonham Carter and Sam Claflin, so it’s no surprise that Netflix viewers were quick to check out the film – so much so that it soon became Netflix’s most popular movie.

After just one day of release, Enola Holmes shot near the top of the Netflix Top 10 list, which offers a snapshot of what’s popular on the streaming site each day (via ComicBook.com).

Currently, Enola Holmes is in second place, behind Ryan Murphy’s new TV show and Sarah Paulson vehicle Ratched, making it the most popular film on the site today.

Of course, Netflix hasn’t released any official viewing figures for the film just yet, but given its early popularity, we wouldn’t be surprised to see it do huge numbers and end up as one of the site’s biggest movies.

And who knows – maybe that success will mean Enola will return in a sequel to solve another mystery and continue to give her older brother some competition in the quest to become the world’s greatest detective.

Meanwhile, Hunger Games star Sam Claflin, who plays Enola’s other brother Mycroft, was full of praise for his co-star Millie Bobby Brown, who produced the film as well as starring in it.

“She doesn’t feel young at all. She handles the pressure better than anyone else I know, really. It’s quite incredible to see. She’s just a powerhouse,” he told Digital Spy.

“She’s so charismatic, so funny, so charming, so intelligent, so wonderfully energetic and vibrant. She brings a lot to a film set. It was genuinely a pleasure working with her. I think she brought out my inner child as well. It allowed me to be a bit more stupid.”
