Credit: SeaWorld OrlandoOrlando does Halloween unlike anywhere else in the country.
By late summer, the announcements start coming in waves. Universal drops house lineups for Halloween Horror Nights. Disney confirms showtimes for Mickey’s Not-So-Scary Halloween Party. Smaller haunts around Central Florida are starting to tease their own concepts. If you live here, or if you plan a fall trip around this stuff, this is the stretch where the season stops being an abstraction and starts becoming a schedule you have to build.
And every one of these events has an identity. Halloween Horror Nights leans hard on licensed properties, typically running four IP houses alongside its originals. Disney goes family-friendly with trick-or-treating and villains. Howl-O-Scream at SeaWorld has always been the one that did neither.
For more than 25 years, Howl-O-Scream built its entire identity around original monsters, original stories, and original haunted houses. No licensed franchises. No recognizable movie titles on the marquee. Just whatever the entertainment teams could dream up, usually with smaller budgets and fewer resources than the biggest Halloween events in the industry.
That run ends this fall.
SeaWorld Adds Its First Major Licensed Horror House
SeaWorld has announced I Know What You Did Last Summer, one of the first licensed horror franchises ever featured at Howl-O-Scream.
SeaWorld Orlando, SeaWorld San Diego, and SeaWorld San Antonio will each open the new haunted house on September 11.
The attraction is officially titled I Know What You Did Last Summer: The Final Catch, and it is based on Sony Pictures’ original 1997 slasher film.
Guests will walk through recreations of scenes surrounding the Southport massacre, following the group of friends whose attempt to cover up a deadly accident leaves them hunted by the hook-wielding Fisherman. SeaWorld says this is the first time the film has been adapted for a major Halloween event.
United Parks & Resorts CEO Marc Swanson spoke on the addition.
“We’re always looking for new ways to raise the bar on immersive entertainment, and bringing ‘I Know What You Did Last Summer‘ to our Howl-O-Scream events is an exciting milestone for all three SeaWorld parks,” Swanson said.
Why This Is Bigger Than One Haunted House
It would be easy to read this as a single house announcement. It is not.
This marks the end of Howl-O-Scream’s run as a Halloween event built entirely around original and public-domain horror.
That independence has always been one of the event’s real strengths. The teams created their own monsters, their own icons, and their own genuinely strange worlds. There was a grassroots, bootstraps quality to it that let creativity lead in a way the bigger-budget events sometimes cannot. When you are not paying licensing fees and answering to a studio, you can chase a weirder idea.
SeaWorld Orlando’s new dark romance scare zone is a good example of exactly that kind of original thinking, and it is the sort of concept that made Howl-O-Scream feel distinct.
Busch Gardens Is Getting a Licensed House Too
“I Know What You Did Last Summer” is not the only licensed property entering Howl-O-Scream in 2026.
Busch Gardens Tampa Bay and Busch Gardens Williamsburg are each introducing separate haunted houses inspired by Anaconda.
That split is worth noting because Howl-O-Scream originated at the Busch Gardens parks before expanding across SeaWorld’s portfolio. The three SeaWorld parks get I Know What You Did Last Summer. The two Busch Gardens parks get Anaconda.
Add it up and Sony Pictures franchises will appear at all five U.S. Howl-O-Scream events in the very first year licensed horror enters the brand. That is not a cautious toe in the water. That is a company-wide shift.
What Fans Are Worried About
The concern circulating among longtime Howl-O-Scream fans is not that I Know What You Did Last Summer will be bad. The Fisherman is a legitimately strong horror villain, and a slasher with a hook and a coastal setting translates well to a haunted house.
The worry is about what happens over the next several years.
Licensed franchises pull attention and sell tickets. That is why the biggest Halloween events lean on them. But the more slots that go to IP, the fewer go to the original concepts that gave Howl-O-Scream its personality in the first place. Howl-O-Scream never needed a recognizable movie title to build a memorable house, and those original ideas were a genuine point of differentiation in a crowded market.
SeaWorld has not indicated that originals are going anywhere. Each event will continue to feature original houses, scare zones, entertainment, and themed bars alongside the licensed additions.
Still, an uninterrupted era has ended. The hope among fans is that these franchises supplement the weirder homegrown ideas rather than slowly crowding them out.
What You Need to Know Before You Go
The new I Know What You Did Last Summer houses debut September 11 at all three SeaWorld parks.
Ticketing differs by location, which trips people up. Howl-O-Scream is separately ticketed in Orlando and San Diego. In San Antonio, it is included with regular park admission.
If you are planning an Orlando Halloween trip that already includes Halloween Horror Nights and Mickey’s Not-So-Scary Halloween Party, Howl-O-Scream has historically been the value play of the three, and adding a licensed house does not change that math.
What to Watch This Season
The interesting question for 2026 is not whether this house is good. It is how it sits next to the originals.
Howl-O-Scream spent 25 years proving you could build a strong Halloween event without borrowing anybody’s characters. This year it finds out what happens when it does both at once.
If the licensed houses raise the event’s profile and bring in guests who then discover the original mazes, this works out for everyone. If the originals start getting squeezed, longtime fans will notice fast.
September 11 is when we start finding out.
