The following scene is from the movie The Terminal. I think it shows a great representation of an ontological crisis. This scene is near the beginning of the movie.
I see many parallelisms between this clip and any regular ontological crisis we might have, for example: the fact that Viktor can't communicate clearly highlights the lack of understanding we face when thrust into a difficult situation. In this scene, Viktor doesn't yet realize the full weight of his situation.
If you guys haven't seen the movie, it's pretty good. It gives a humorous look at hard times that we all come across in life.
