Besides Princess Diana and Prince Charles, the Duchess of York, Sarah Ferguson, also stood beside Maj. Hugh Lindsay's wife Sarah, at the RAF Northolt tarmac. Both women were pregnant at the time.
Prince Charles is seen writing with his left hand when in reality he is a right handed.
Although Diana's dance on the stage of the Royal Opera House is stated to be for Charles' 37th birthday on November 14, 1985, in real life it occurred on December 23, a month and a half later. The Klosters resort avalanche took place nearly two and a half years later, in March 1988, and not just a few days later as portrayed.
Diana's present to Prince Charles is recorded on a T-120 videocassette, which was sold in the US/Japanese market where they had the 60 Hz NTSC television standard. In the UK at the time, the 50 Hz PAL colour television standard was in use, and videocassettes had different labelling, beginning with E (E-180, E-240, etc.). The T labels were not available in the UK at the time.
Major Hewitt is seen wearing the rank insignia of a captain.
