Episode 3 - drivel
First off, the glaring props mistakes that I spotted - and I'm sure others would find more
1, a Radiomobile car radio from the 60s in 1956
2, a carpet of the 60s in the flat of Lyons
3, a lightswitch of the 60s in the flat of Lyons
4, telephone poles with modern multi-core wires on them (a different camera angle could have missed them entirely).
The dreadful fight scene on the stairwell, where we are meant to believe a 90lb weakling overpowered a professional assassin, who then topped himself rather than spill the beans. I was shouting at the telly.
Utter tosh.
