Nathan Fillion is part of a successful Dungeons & Dragons series on Prime Video that belongs to a universe that gets high fantasy right in every possible way. Prime Video is one of the many streaming services that have gone down the rabbit hole when it comes to the fantasy genre. With higher budgets and fewer episodes, fantasy shows have thrived lately. While HBO has the Game of Thrones TV shows, Netflix has The Witcher, and so on. Prime Video's library of TV shows has grown to include both live-action hits and animated masterpieces. In the live-action realm, the streamer's most ambitious show is The Lord of the Rings: The Rings of Power. The streaming service is also the home of the book adaptation The Wheel of Time. Where Fillion comes into the story is in the animated realm. Usually, the actor tends to be tied to other genres, including sci-fi and crime. In those genres, Fillion has appeared in projects like Firefly, Castle, Lanterns, The Rookie, and many more. In animation, Fillion is working on a Firefly sequel series, with the actor also having voiced the Green Lantern Hal Jordan in DC animated movies. Choose the movie with the higher Rotten Tomatoes score. Prime Video is the home of two major high fantasy series, the animated The Legend of Vox Machina and The Mighty Nein. Both of those are based on Critical Role's Dungeons & Dragons campaigns, set in their own world of Exandria. The Mighty Nein was the second animated high fantasy series from that universe to arrive on Prime Video, and it is a genre masterclass, with Fillion involved. Nathan Fillion Has A Small Role In The Mighty Nein Fillion does not voice one of the characters in The Mighty Nein's main roster, which is made up of Critical Role cast members like Laura Bailey and Ashley Johnson. That said, the actor does play an important role in The Legend of Vox Machina spin-off series on Prime Video. Fillion gives life to The Gentleman in The Mighty Nein, with his character being a powerful crime boss in Zadash. The Mighty Nein sees the party engage with him to get a new concealment amulet for Caleb, having to first retrieve an arcane compass for Fillion's character. The Gentleman appears in multiple episodes. Fillion was perfect casting for the role. First, the actor is a beloved star for his voice work over the years, playing Green Lantern for DC multiple times in animation before he gave life to Guy Gardner in James Gunn's live-action Superman movie, and also voicing characters in projects like Monsters University, Cars 3, Rick and Morty, M.O.D.O.K., and more. Then, there is the fact that the actor has impeccable comedic timing, which a role like The Gentleman and the world of Exandria are perfect for. Finally, Fillion's history in crime shows allows him to make The Gentleman an enigmatic and dangerous figure. The Legend Of Vox Machina And Mighty Nein Are High Fantasy Done Right Both The Mighty Nein and the Prime Video high fantasy universe's first series, The Legend of Vox Machina, are universally acclaimed genre series. On Rotten Tomatoes, the latter stands at a rare, perfect 100% critics' score and a stellar 93% audience score. The Mighty Nein also boasts a pitch-perfect 100% critics' score, with an excellent 89% audience score. The Prime Video high fantasy shows make the most of the genre in animated form, where they are not limited by the budget constraints that a live-action series would have. Due to that, The Mighty Nein is able to soar. Critical Role's Prime Video universe is a masterclass in high fantasy due to its immersive original world of Exandria, which is filled with monsters, different classes of characters, intricate and splashy magic systems, surprising ancient secrets, and more. All of those larger-than-life elements are grounded by cunning games of politics and emotional character arcs. The latter is how The Mighty Nein and The Legend of Vox Machina truly shine, crafting characters that are not only multi-layered, but also come with their own diverse backgrounds, and have entertaining dynamics within the party. The Mighty Nein is vibrant, action-packed, emotional, and just a masterclass in high fantasy storytelling.
