That episode of "Casualty" filmed in one take

The story was fairly typical "Casualty" fare, but on a technical level it was superb.

The son and I looked out for a reflection of the cameraman in mirrors etc, nothing. The bit where the cameraman is lowered over a banister was especially awesome.

They used to have very long shots in "ER" as well, but only three or four minutes, not a whole hour.
