If you've seen Mesrines and liked that then give this a shot. At this price it is superb value for both the film cut and three part tv version.
If you are of a certain age (as I am) then Carlos is one of the bogey men of history. As the film says treat it as a fiction not a drama documentary but it is still grounded in the actual events of the time. Plenty of drama, plenty of contradictions. Interesting viewing.
