The three-minute YouTube short Open Door, which has accumulated nearly 15 million views on social media, will be adapted into a feature-length movie. Creator Kevin Cate and producer Rick Kearney will develop the project through Cate’s Clinging Vine Films, following the recent trend of viral online content being transformed into theatrical releases.
The announcement comes after YouTube-to-film adaptations have proven their commercial viability, with projects like Backrooms and Obsession achieving significant box office success. Open Door depicts a terrifying elevator ride shared by two people, a premise that has captivated millions of viewers and generated consistent demand for an expanded story.
The Growing Trend of YouTube-to-Film Adaptations
The Open Door adaptation joins a wave of YouTube content making the leap to feature films. Backrooms director Kane Parsons became the youngest director to top the box office with his adaptation of the viral internet phenomenon. Meanwhile, Obsession became the highest-grossing movie acquired out of a film festival, demonstrating the commercial potential of content that first finds its audience online.
These successes have created a new pathway for independent creators to develop their work into larger productions. The formula appears straightforward: viral online content proves audience interest exists, which then attracts investment for expanded versions of the original concept.
Kevin Cate and Rick Kearney have previously collaborated on adapting Cate’s Unbearable Christmas, establishing a working relationship that will continue with the Open Door project. Their production company, Clinging Vine Films, will lead the development of the feature adaptation.
What We Know So Far
The original Open Door short runs three minutes and is currently available for streaming on its official site. The film depicts an elevator encounter between two people that takes a frightening turn. While the short has generated nearly 15 million views across social media platforms, specific details about what the characters experience in the elevator have remained a mystery that viewers continue to ask about.
Cate addressed the ongoing curiosity from fans directly. “I literally can’t go a day without someone asking me what our characters saw down there. And I really, really can’t wait to show everyone — and give some hints along the way,” he said. “We are ride or die with our original cast and crew who made this all happen.”
The commitment to the original team suggests continuity between the short and the feature adaptation, though specific cast members for the expanded production have not been announced. Cate emphasized the quality of the material being developed: “And we’ve written some of the most incredible roles to make this a next-level project. Right now, it’s just a matter of showing the demand and finding our village.”
When asked about the adaptation opportunity, Cate responded simply: “Only in my wildest dreams.”
Kevin Cate’s Background
Before establishing himself as a filmmaker, Kevin Cate had a career in political communications. He worked as a Democratic consultant and served as a campaign spokesperson for Barack Obama in 2008. His father is Keith Cate, an anchor for WFLA.
This transition from political consulting to filmmaking represents a significant career shift, with Cate now focused on developing horror and thriller content through Clinging Vine Films. The success of Open Door has accelerated his profile as a creator capable of generating viral content that resonates with mass audiences.
What Happens Next
The feature film does not yet have a confirmed release date. Based on typical production timelines, the earliest potential release could be 2027, though this remains speculative and dependent on various factors including financing, production schedules and distribution arrangements.
The project is currently in development, with Cate’s comments suggesting that securing additional support and demonstrating audience demand remain priorities. The short’s nearly 15 million views serve as evidence of interest, but the transition from online short to theatrical feature requires additional partnerships and resources.
No specific budget information, filming locations or production schedule details have been announced. The project also has not announced distribution arrangements, meaning how and where audiences will eventually see the completed feature remains undetermined.
The Success Model for YouTube Adaptations
The pathway from viral YouTube content to theatrical release has become increasingly established. Backrooms demonstrated that internet-native horror concepts could translate into box office success, with Kane Parsons achieving the distinction of becoming the youngest director to lead the box office charts.
Obsession’s performance as the highest-grossing festival acquisition further validated the model, showing that content with proven online audiences can achieve commercial success through traditional distribution channels.
For creators like Cate, these precedents offer both a template and proof of concept. The challenge lies in maintaining the qualities that made the original content successful while expanding it to feature length without diluting its impact.
The Original Short Film
Open Door’s three-minute runtime packs a concentrated horror experience centered on an elevator setting. The confined space creates natural tension, while the mystery of what the characters encounter has driven viewer engagement and repeated requests for explanation.
The short is currently available for streaming on its official site, allowing audiences to experience the original content while waiting for the expanded adaptation. The accessibility of the source material contributes to ongoing interest and allows new viewers to understand the anticipation surrounding the feature development.
