Big Texas Terror 2026 in San Antonio will feature Art the Clown actor David Howard Thornton
A horror convention returns downtown with a “Terrifier” focus and a broader genre lineup
Big Texas Terror, a horror-focused fan convention presented under the Big Texas Comicon umbrella, is scheduled to return to San Antonio on March 6–8, 2026, at the Henry B. González Convention Center. Organizers have listed the event in the convention center’s public calendar and are selling multi-day and single-day tickets for the three-day run.
The headline announcement for the 2026 edition is the planned appearance of David Howard Thornton, the actor who portrays Art the Clown in the “Terrifier” film franchise. Event materials describe Thornton as appearing across all three days, with an in-costume photo opportunity planned for Saturday, March 7. A cast-focused “Terrifier” panel is also advertised for Friday night with multiple performers from the films.
Dates, venue and hours
When: Friday, March 6 through Sunday, March 8, 2026

How ticketing and celebrity add-ons typically work
Organizers are offering multi-day and single-day admissions, including upgraded tiers that bundle benefits such as line-skip or priority seating. Event information also notes that celebrity autographs and professional photo ops are priced separately from general admission. The convention’s FAQ indicates many guest tables primarily accept cash and that on-site ATMs are planned.
Programming: guests, vendors and fan experiences
Beyond the “Terrifier” talent, promotional materials for the 2026 show describe a broader roster of genre guests spanning film and television. The event is also marketed as a large vendor-and-artist floor, with applications for exhibitors and artists posted for the 2026 edition. The convention center’s event listing includes an attendance estimate of roughly 2,500 people.
Big Texas Terror has positioned itself as a dedicated horror convention in the same downtown venue that regularly hosts pop-culture events, emphasizing celebrity panels, photo ops and a vendor hall.
Context: a growing calendar for horror fandom in San Antonio
Big Texas Terror launched in San Antonio in 2025 as a new horror-branded convention weekend and is now returning with an expanded run from two days to three. Its March scheduling places it apart from the city’s fall-heavy haunted attractions and Halloween-season events, giving horror fans a major gathering outside the traditional “spooky season” window.
Organizers have not released a full, time-stamped panel schedule in the public materials reviewed, and appearance details can change due to travel or production commitments. Attendees are encouraged to confirm final schedules and any guest updates before making plans.
