Character mistake: Sasha refers to the 'murder' on Thursday 4th June 1982. The date in question was on a Friday.
Factual error: In the flashback scene to Peggy's wedding in 1956, the wedding car, a Ford Consul, is a 1959 model, and the car behind it is a standard Goldstar which started production in 1957.
Continuity mistake: In the first night shot, the shard is not completed. In the next daytime shot it is complete.
