5 movies feature this trope

Over Your Dead Body
Dan and Lisa arrive as active enemies with lethal plans against each other — the clearest possible prior conflict. The escaped convicts are a shared external threat neither could survive alone, forcing them to set aside their mutual murder schemes. They fight side by side using improvised weapons; cooperation is the direct and only mechanism of survival. The shared threat is explicitly larger than any marital grievance, and former enemies are literally fighting together in the climax.

Desert Warrior
The tribes are explicitly described as 'warring, distrustful' before Hind's campaign. She travels the peninsula delivering a unity speech to each leader. Victory at Dhu Qar is impossible without the coalition — no single tribe could face the Sassanid army alone. Former rivals fight side by side in the climax, and the shared imperial threat is framed as larger than any inter-tribal dispute.

No Ordinary Heist
Richard and Barry intensely dislike each other but are forced to set aside their antagonism when criminals kidnap their families. The shared threat is explicitly larger than any workplace grievance; neither man could manage the internal heist operation alone given their separate roles (manager vs. security guard). They work side by side through the operation, and their bond is explicitly transformed by the cooperation. Four signals fire: rivals put aside conflict, victory impossible without both, shared threat dwarfs internal dispute, and former antagonists act together in the climax.

Project Hail Mary
Two species from entirely different star systems — humans and Eridians — face the same existential astrophage threat and cannot solve it alone. Grace and Rocky, representing their respective civilizations, set aside vast biological and communicative differences to cooperate. Victory for both worlds is impossible without their cross-species partnership.

Panda Plan: The Magical Tribe
Fierce rivalries among tribal factions — a capricious wind-wielding leader, warrior Qiang Shan, and Prince Tu Lu — are the ongoing obstacle. Jackie must navigate these competing agendas and guide the factions toward solidarity. Unity and shared compassion are the necessary condition for the storm to be dispelled; no single faction could have averted the disaster alone. Former rivals must cooperate for the resolution to occur.
