I found a video of a large asteroid impacting Earth:

Is it at all realistic?

This video does seem to make the rounds, at least this time they fixed the size of the asteroid or it is a planetesimals. Originally it was suppose to be a 50 mile wide impactor, which was bogus. But that being said, the effect are seem to be and probably are accurate (with some artistic license ) The oceans would boil away and the crust would become molten. One thing not shown, is that there should be terrain deformation on the far side of the impactor. Either way if you were around you would be in for a very bad day.

--- edit ---

The asteroid itself sort of glows as well, before the impact (or at least seems tectonically active) which is obviously bogus.

Since physics hardly matters for media people, the glow probably was to make the asteroid look more "malicious"

This video has better music.

[sarcasm]You mean a 8.4 gram bullet traveling at 1,410 feet per second wouldn't really knock a person ten feet backwards? How dare those movie people lie to us. [/sarcasm]

Anyway IMO the The asteroid/planetesimals could/would be glowing providing it was recently formed form another impact. The glow would be residual heat from its formation.

It could, but than it wouldn't have this ancient cratered surface, would it

I think that's actual footage from the ISS...
