TriStar Pictures has pre-emptively acquired feature rights to Trevor Henderson’s viral internet horror “Cartoon Cat,” according to an insider with knowledge of the project. It is the second major deal Henderson has landed this month after “Siren Head” moved to Warner Bros following a five-studio bidding war.

The stakes here are immediate and very boardroom. When “Siren Head” drew a five-studio scramble and “Cartoon Cat” now lands via a pre-emptive rights grab, it signals the market is treating viral IP like a front-loaded risk, not a long shot. If you are an executive deciding whether to fund development on something that started online, the real question is no longer “Is this cool?” It is “How much are we willing to pay to not lose it to the next buyer in line?”

In “Cartoon Cat,” the premise is built to translate internet dread into feature scale. Deadline describes the menacing cat as an ancient hollow rot that uses the collective human awareness and memories of old cartoons as a passageway to manifest into our reality, and then wreak violent havoc. That is not the kind of sentence studio executives skim past; it frames a creature as a concept that can be represented visually, expanded narratively, and used as a rules-based horror engine. In other words, it is the kind of IP that lends itself to franchise mechanics, even if the origin is a meme-adjacent horror character.

The project also comes with a lineup of producers that tells you TriStar is not just buying a headline. Producing the “Cartoon Cat” feature are Roy Lee, Steven Schneider, Scott Glassgold, and J. Todd Harris, along with Thomas Pettinelli and Marc Marcum. Roy Lee is the kind of name investors and development teams recognize for turning high-concept genre material into scalable productions. Steven Schneider, Scott Glassgold, and J. Todd Harris bring additional heavy lifting experience, while Pettinelli and Marcum add more production muscle. The combined effect is that TriStar is signaling it intends to move from rights acquisition to actual filmmaking momentum quickly, rather than treating this like a passive option.

For context, the “Siren Head” deal is the mirror image of what happened here. TheWrap reports that “Siren Head” landed at Warner Bros after a five-studio bidding war. That earlier scramble involved Zach Cregger and Brian Duffield as co-writers, with Duffield directing. Producing that “Siren Head” project were Roy Lee, Steven Schneider, and Scott Glassgold, along with J. Todd Harris, and also Thomas Pettinelli and Marc Marcum. In other words, Henderson’s IP did not just win attention; it pulled multiple studios into direct competition, and it appears TriStar is trying to avoid the same kind of auction dynamics on “Cartoon Cat.”

It is worth noting what TheWrap does and does not say. Reps for TriStar did not respond to TheWrap’s request for comment. So we do not get a pricing number, a timeline, or any strategic quote explaining the pre-emption. But the pattern itself is actionable. Pre-emptive buys typically reflect a belief that the asset will attract more bidders if it remains on the open market. In that setting, the “regulatory background” is less about government approvals and more about internal governance. Studio boards, investment committees, and deal desks must justify spend without full certainty on screenplay, casting, and audience conversion. Viral horror can reduce the uncertainty around awareness, but it increases pressure around brand stewardship. If the horror community expects a certain vibe and the production team veers off, the backlash is swift online. That makes acquisition strategy only half the story; the other half is execution.

Second-order implications show up fast in a world where attention is a currency. Henderson is effectively demonstrating a pipeline: characters catch fire online, studios feel the demand signal, and multiple buyers are willing to pay for the chance to be first to adapt. For peer executives, this pressures development teams to rethink what counts as “proof.” Traditionally, a script, a packaged director, and internal confidence might come before major spend. Now, the proof can be the internet itself, and the spending can happen earlier. That can advantage companies with strong dealmaking, fast decision cycles, and the ability to staff production quickly.

For boards and senior leadership, the strategic stake is simple: being late to viral IP can cost you the asset, but being early can cost you control. TriStar’s pre-emption of “Cartoon Cat” is a reminder that studio competition is no longer confined to traditional properties with years of downstream tracking. It is increasingly about who can translate viral demand into film pipeline certainty before the next studio makes the same move.
