context: A short time after the episode aired, the producers received a letter that was written by the family of one Felix Reese, who himself was a taxi driver who was shot in the head by Leslie Grantham (the actor playing Col. Mustard) while the future star of EastEnders was a soldier stationed in Germany.
source: The Reeses found it distasteful that someone who performed an illegal killing as a soldier would be cast as someone who performed an illegal killing as a soldier.
reference_original: Die Reeses fanden es geschmacklos, dass einer, der als Soldat einen illegalen Mord begangen hatte, die Rolle von einem erhielt, der als Soldat einen illegalen Mord begangen hatte.
reference_flipped: Die Reeses fanden es geschmacklos, dass eine, die als Soldatin einen illegalen Mord begangen hatte, die Rolle von einer erhielt, die als Soldatin einen illegalen Mord begangen hatte.
