See the Interstellar robots TARS and CASE behind-the-scenes as practical effects puppets, not CGI

This behind-the-scenes video shows how they designed and made the robots in Christopher Nolan's great sci-fi film

Seeing as how I just watched Interstellar while home sick this past week, this video could not have come at a better time. Two of the best characters in the film were the robots, TARS and CASE. Considering they were robots, the two characters were just as human as everyone else, provided some great humor, and were in almost all the best moments.

I was under the assumption that they were almost entirely CGI, when, in reality, they were actually created by the special effects team. Most of the scenes were practical effects. TARS and CASE actually had people behind them, and in some cases vehicles. How Christopher Nolan and his team came up with the ideas of how they should look, move and act, and then design them so they could function, truly stuns me.

The best part is when it shows how TARS operated on the water planet.
