A24 has released the first trailer for Onslaught, and it puts UFC star Alex Pereira in a very different kind of spotlight. Pereira plays The Butcher in the film, which is set to reach theaters on Sept. 4.
The trailer is drawing attention now because Pereira is not just a recognizable face from combat sports. He is one of the UFC’s biggest stars, and he is scheduled to return to the Octagon on June 14 against Ciryl Gane for the interim UFC heavyweight title. That matchup gives the trailer an added lift, with his fight career and screen role arriving in the same news cycle.
Onslaught is an A24 release and IMDb lists it as an action, horror and thriller film. Its plot centers on a mother living in a trailer park who uses her skills to protect her loved ones after a threat escapes a secret military base, while mercenaries try to contain it. Pereira’s role as The Butcher is a striking detail in that setup, even if the trailer leaves open how central he will be once the movie arrives.
That is the real hook for audiences watching this rollout. Pereira is known for fighting, not acting, yet here he is in a trailer for a movie built around survival, danger and a figure named The Butcher. The next fixed date is June 14, when he steps back into the cage, and then Sept. 4, when the film itself is due out.
