This almost documentary style film made for interesting viewing, and this may have been Luke Evans' first leading role, and he grabbed the opportunity with lots of panache. As the leader of the band of robbers who pulled off the heist, I had some difficulty in focusing on who he was as Buster Edwards and Ron Biggs were always better known. The film however did show that this was a big gang of thieves, and this probably led to their undoing. The actual heist took up little screen time, the rest dealt with the dynamic between the gang, and the motivation of the ringleaders apart from the usual greed, is clearly shown. I enjoyed it, there was always the feeling that this was a gang who were in over their heads, and there is one telling moment when they realize it after counting the money.
The early sixties setting with its talk of the war years and exploits of that time is well realized, making this a series to be enjoyed. Martin Compston had a small but significant role as well.
The second instalment is just as fascinating when you are given the opportunity to see the trail of clues the gang left behind them in the old farmhouse, even after 'apparently' cleaning up! A restrained but driven Jim Broadbent gives the sense of urgency the Police felt about solving this crime, and it says much about the actors concerned, that you almost wanted the robbers to get away with it! Perhaps that explains the success of later series like Money Heist which focus on that.
