Felipe Castanhari
Himself - Host

Host Felipe Castanhari explores science, history, mysteries and marvels, uncovering mind-blowing facts with help from his lab buddies.
I remember the first time I saw Beakman’s World in the early ’90s. The show was a revelation: a man in a lab coat and bowtie, surrounded by bubbling beakers and oversized props, explaining science with the kind of enthusiasm usually reserved for birthday parties. It wasn’t just educational—it was fun, the kind of fun that didn’t feel like homework. Mystery Lab, Felipe Castanhari’s Brazilian Netflix series, feels like a direct descendant of that spirit.
But here’s the thing: it’s not just a copy. It’s a love letter to that era of television, one that’s trying to figure out how to make science feel alive in a world where kids (and adults) are more likely to learn from YouTube algorithms than from Saturday morning TV.

The show’s premise is simple: Castanhari, a YouTuber known for his nostalgia-driven content, hosts a series that blends documentary-style explanations with the energy of a sitcom. Each episode tackles a different mystery—time travel, the Bermuda Triangle, artificial intelligence—and breaks it down with a mix of direct-to-camera segments, animations, and lab experiments. It’s Bill Nye the Science Guy meets The Office, if The Office were set in a lab and everyone wore lab coats (or, in the case of Betinho, the janitor, a jumpsuit that’s seen better days).
What’s striking about Mystery Lab is how earnestly it commits to its tone. There’s no irony here, no winking at the camera to let you know the creators are in on the joke. Castanhari and his team—Dr.
Thay (Lilian Regina), the no-nonsense scientist, and Betinho (Bruno Miranda), the bumbling but lovable janitor—play their roles straight, even when the humor veers into the kind of broad comedy that feels like it’s aimed at 12-year-olds. And that’s where the show’s charm lies: it’s unapologetically silly, but it’s also unapologetically smart. The animations, in particular, are a standout.
"A fun, science-driven show that blends education with entertainment, though some find its approach too simplistic."
Viewers appreciate the engaging mix of science, mystery, and humor, with Felipe Castanhari’s hosting and hands-on experiments standing out as highlights. However, some feel the explanations are too basic for those with prior knowledge, and the pacing can drag in places. latestnetflix.com's read is that the family-friendly tone makes it accessible, but it may not satisfy those seeking deeper scientific analysis.
Netflix Brasil posted the official trailer on 24 July 2020. Seventy-six seconds. The host is Felipe Castanhari, the YouTuber from Canal Nostalgia, not Manual do Mundo, the other Brazilian science channel people keep mixing him up with. Revista Galileu ran the clip the same morning and named the set Complexo Curie. Dra. Tay is Lilian Regina. Betinho, the caretaker who hangs around the experiments, is Bruno Miranda. The talking supercomputer B.R.I.G.G.S. is voiced by Guilherme Briggs, the dubbing regular who has put Portuguese on Hollywood faces. Galileu also printed that astrophysicist Gustavo Rojas, a columnist there, consulted. latestnetflix.com's view is that metrópoles added that professors, doctors, and researchers sat on the episodes, and that Castanhari was dared, in the promo, to pitch the whole series in thirty seconds., ,
The English card is Mystery Lab. The Portuguese title is Mundo Mistério. Netflix dumped all eight episodes on 4 August 2020. Runtime sits around thirty minutes. TMDB marks the series ended after that one drop. Wikipedia lists the companies as Estilingue Filmes, Polar Filmes, Psycho N Look, and Webedia. The Portuguese wiki names André Lefcadito as director. Castanhari created the show and hosts it. He, Fernando Lefcadito, and Renata Galvão sit as executive producers. Wendel Bezerra turns up as Raul Gordon. ,

Sidcley Lyra, writing for Ciência Hoje from Fiocruz's Casa de Oswaldo Cruz, treated the series as a bigger, more animated cut of Castanhari's old Nostalgia ciência segments. Storytelling, cartoons, and location bits aimed at mysteries people still pin on the supernatural. Lyra framed it as a shove against denialism and conspiracy talk, covering physics, microbiology, evolution, computing, and ecology.
The episode list is public and loud. Bermuda Triangle disappearances. The Black Death and its twenty million dead. Time travel. How wolves became dogs. A zombie apocalypse, if it were real. The great extinction. Superintelligent AI. A finale that asks whether global warming is a big conspiracy. Wikipedia, TMDB, and Netflix's own titles line up on that slate. , ,
There was no second season announcement from Netflix. TMDB's status is ended. Fan notes on IMDb, which are not reporting, groused that Betinho felt childish next to Castanhari's YouTube hour and that the lab comedy got in the way of the science. That is viewer chatter, not a trade fight or a firing. What sits on the record is the bet. Netflix took a Brazilian YouTuber, built him a named lab, hired Briggs, consulted Rojas, and shipped eight Portuguese explainers in a single night. The trailer is still on YouTube. , , ,
