Apple Original Films releases first trailer for “Mayday,” a Cold War buddy action comedy starring Ryan Reynolds and Kenneth Branagh

Apple Original Films has released the first trailer for “Mayday,” an action-buddy-comedy set against a Cold War backdrop, starring Ryan Reynolds and Kenneth Branagh. The studio announced the trailer drop as the film heads toward its Apple TV release date of September 4.

In “Mayday,” Reynolds plays Lieutenant Troy “Assassin” Kelly, described in the trailer materials as a hot-shot U.S. Navy pilot whose mission goes sideways when he is sent behind enemy lines. The premise presented in the trailer centers on the challenge of surviving hostile territory while relying on a partner dynamic to get through the mission.

Branagh is also featured prominently as a co-star in the project, which positions the film as both action-oriented and character-driven, blending suspense from the enemy-lines setting with a comedy approach built around the buddy framework. The trailer’s early cut emphasizes tension and constraint alongside moments intended to defuse the pressure of the situation.

Deadline’s preview of the trailer frames “Mayday” as an Apple Original Films release and identifies it as an upcoming hybrid of action and humor, aimed at viewers looking for a mainstream streaming event rather than a theatrical-only release. The September 4 date places the title on the calendar well ahead of the fall television and streaming season, when platform releases often compete for attention.

Details on the supporting cast, character names beyond Reynolds’s role, and the full plot are not laid out in the trailer description provided by Deadline. As a result, the specific nature of the “enemy lines” scenario, the timeline of the mission, and how the buddy partnership develops are likely to be clarified closer to release or in additional promotional materials.

Apple TV viewers will be able to watch “Mayday” starting September 4, following the trailer rollout. For now, the film’s marketing is focused on the central hook, a U.S. Navy pilot trapped in hostile territory, and the star power of Reynolds and Branagh as the basis for a genre blend.

The trailer’s release also indicates Apple Original Films’ continued push into broad-audience entertainment on its streaming platform, using recognizable movie stars and premise-led storytelling for calendar-timed launches. With the first trailer now public, the next round of marketing typically includes additional footage, cast information, and promotional interviews that fill in the story beyond the initial mission setup.
