* A planetwide version happens offscreen, but sensed by Obi Wan Kenobi in ''Franchise/StarWars: Film/ANewHope'':
-->"I felt a great disturbance in the Force, as if millions of voices suddenly cried out in terror [[EarthShatteringKaboom and were suddenly silenced]]. I fear something terrible has happened."
** The movie's manga adaptation makes a point of portraying that one exact Mass "Oh, Crap!"
** In a similar vein, ''Franchise/StarWars: Film/TheForceAwakens'' provokes this reaction across the galaxy when Starkiller Base fires its weapon for the first time. [[spoiler:Not only do we see the Mass "Oh, Crap!" from the people in the Hosnian system, but because it's a hyper light speed weapon, the blast is visible from outside the system. The people on Takodana aren't fully aware of what's just happened, but they can tell it's ''bad''. Only Finn, Han, Chewbacca and Maz have any idea what that light in the sky was, and they are horrified.]]

* In ''WesternAnimation/OliverAndCompany'': Sykes kidnapping Jenny elicits this reaction from Fagin and his dogs.

Sometimes serious, but often a comedy trope. When faced with something, most or all cast members in the scene ''[[OhCrap panic]]''. Related to CrowdPanic, except it's not about the LivingProp characters. Expect TheStoic or OnlySaneMan to get everyone to shut up for long enough to deal with the problem, if they don't, [[OOCIsSeriousBusiness the scenario is treated very seriously.]]

* ''[[Film/TheNakedGun The Naked Gun: 33 1/3]]'': From the same creators as ''Sirplane'' above, this film showcased this during a confrontation on-stage at the Oscars between Drebin and Rosco. Rosco's got a gun, Drebin has the bomb Rosco wants to trigger. Drebin's solution? Trade the gun for the bomb. Cue {{FacePalm}}s from ''everyone'' with their hands free.
