|---|---|
| 1985 | Original ThunderCats series debuts |
| 1989 | Original series ends |

Since the original series ended in 1989, there have been two revivals: Cartoon Network’s Thundercats in 2011, which was unceremoniously cancelled after just one season, and then ThunderCats Roar, in 2020.
Is This Adam Wingard’s Movie or Something New?
Here is where it gets messy.
Previously, Adam Wingard was attached to direct a separate live-action movie, and recently confirmed the project is still in development, but the animated movie is likely to land sooner.
As of March 2024, Wingard was calling his “ThunderCats” movie a “priority” and was writing the script with longtime creative partner, Simon Barrett.
According to The Playlist, it remains unclear whether Wingard is still attached or if this is a completely separate project thundercats animated film news.

Why Is Warner Bros. Going Animated First?
The math is brutal.
Masters of the Universe was backed by a similarly popular 1980s IP, and has only just passed $100 million at the box office, despite a reported production budget of twice that.
Henry Cavill’s live-action Voltron, another 80s property also set up at Amazon, is not bothering with theaters at all. It is headed straight to Prime Video in 2027.
| 80s Reboot | Format | Result |
|---|---|---|
| Masters of the Universe | Live-action | Just crossed $100M vs $200M+ budget |
| Voltron | Live-action | Skipping theaters, Prime Video 2027 |
| ThunderCats | Animation | Smart, lower-risk hedge |
Animation lets Warner Bros. deliver the scale the property needs, from Third Earth to the Sword of Omens to the full sci-fi-fantasy world, without taking the same nine-figure live-action swing that just torched He-Man.

The ThunderCats Story (Quick Refresher)
The story follows a team of cat-like humanoids (Lion-O, Cheetarah, Panthro, Tigra, Jaga, Wilykit, Wilykat and Snarf) who leave the dying planet of Thundera in search of a new home for their species. They settle on a planet that comes to be known as Third Earth, where they battle Mumm-Ra and their old enemies, The Mutants, for control of Lion-O’s Sword of Omens.
3 Reasons This Animated Movie Could Actually Work
- Lower budget, lower risk: Animation skips the He-Man trap of bloated live-action VFX costs.
- Built-in nostalgia army: Millennials and Gen-X fans are desperate for a faithful adaptation.
- Visual freedom: When you look at it from a purely visual level, it’s basically He-Man meets Cats the musical, and animation solves the uncanny valley problem instantly.
