Harry charges the camera making his O-face.
The last scene of the movie is coming to a close. For some reason, something in the scene - perhaps a flying machine, an object, or even a character - decides to start flying, and comes straight at the camera. Just as it's about to "impact", the scene cuts to black and we go to the credits.
The flying person/object doesn't need to be actually flying, but more often than not, it is.
Most common in special-effects laden movies. After the rise of CGI, this became much more popular, but earlier movies display it as well.
Contrast Riding into the Sunset
where it ends with something moving away from the camera.
This is an Ending Trope
