The Claws of Axos - Episode 2

I wonder why they made a duplicate of Filer, it seems to have almost no purpose whatsoever. Yeah, they sent it to bring the Doctor back, but the Doctor saw through the duplicate immediately. The setup shot of the laboratory is impressive, even though it's probably CSO. The Doctor inveigles his way in so he can use the lab to fix his TARDIS if he can. Nice one, Doctor. Again, Jo has almost nothing to do here. The professor is, I believe, later cast as Colonel Crichton, the Brigadier's replacement in "The Five Doctors". The Master escapes and is evil, even doing almost a Raiders of the Lost Ark stunt to control a truck. Nice to see Delgado doing a bit of stuntwork, riding on top of the truck.
