[Freddy]

Found this interesting. It's surprising what they use CGI for outside of the main action - I mean we're used to seeing animated robots in things like the Marvel movies or Transformers. Like for example they turned a slowly moving river into a fast flowing one. Various trees were added. And it appears that they blow everything up in cyberspace these days, rather than setting fire to things in real life.

It doesn't look like a zombie nor indeed a human ever set foot on the bridge for the shoot.

Cool stuff

Nice find Freddy! That is a much better way of doing it! Didn't have to hire all those Extras, didn't have to risk them getting hurt or paying tons of insurance claims, no worries of destruction of State or County property for the bridge explosion and fire. No disturbing the peace fines from the explosion. No flack from the EPA (Environmental Protection Agency) for the pollution of the river and many more potential issues avoided.
Good stuff!!

Get yer programs here! Ya can't tell the real from the fake without a program!! Programs!!

They did a great job on the final episode (after 9 seasons) with Andrew Lincoln.
