Two wonderful films - Roy Castle showing "If you wanna be the best, if you wanna beat Daleks...Extermination's what you need!"(Apologies to Record Breakers)and Bernard Cribbins making a prophetic early appearance before being regenerated many years later as Donna Noble's grandfather.
Just to add a bit of colour, can I say that, back in 1964/5,I saw the iconic scene from Daleks:Invasion Earth 2150 AD when the Dalek emerges from the Thames being filmed. I was a young lad at the time on my way back home from a cub scouts morning (ah, bless!) and went past the filming area at some old riverside warehouses around the Battersea area. My father and I watched the Dalek being repeatedly dragged out of the river at the end of a thin wire until they got the scene just right.
