Over the New Year holiday, CCTV-4 has been showing the full 48 hours of Deng Xiaoping at History's Crossroads. My favourite bits (i.e. the only stuff I can understand) are the cameo appearances by Robert Maxwell, Ted Heath, Margaret Thatcher and a Governor or two. And only one of them looked anything like the real person.
The there’s the stilted dialogue…and some of the scenes were totally fictitious. We see Thatcher having a cordial meeting with Ted Heath (in 1982?), where she asks him “as her old friend” to talk to Deng about Hong Kong.
Rather unlikely, given that they barely spoke after 1976 (she defeated him in the leadership election in 1975). Yes, Heath went to China and would have talked to Deng about Hong Kong, but the meeting with Thatcher never happened.
But I expect everything else is totally true.
