Okay, hear me out.
An action film where Chris Pine and Sebastian Stan play partners, and Sebastian is in love with Chris but thinks Chris is into their handler, Zoe Saldana.
Chris gets kidnapped/captured and when Sebastian finds out he does that teary-eyed, barely-holding-it-together thing. He goes against orders and - with Zoe’s help covering for him at the agency - tears the world apart to get Chris back, while Chris fights his way out from the inside.
They meet in the middle and everything’s great for like ninety seconds until - PLOT TWIST - it was all a trap to capture Sebastian because he has information they need and the bad guys know he’s in love with Chris. Chris had no idea! Sebastian cries some more.
Of course they escape and destroy the bad guys and save the world and get medals or something, and then Sebastian is like, ‘Look, about the whole in love with you thing, I don’t expect -’ and then Chris just
Right there. In the parking lot of their agency headquarters.
Sebastian cries because he’s so happy, and they make out a little more and then walk to their car holding hands, the first openly gay action heroes in a major summer blockbuster THE END
