Indeed I have; I thought it portrayed the cracking of enigma by the scholarly team led by the somewhat pecular and Asperger's Syndrome-like Alan Turing, of Bletchley, quite authentically. Although I wasn't alive during the time period it seemed to be quite a significantly authentic portrayal. Indeed it was an interesting movie and important part of history... The focus of the cracking of the code in Hut 3 always has led me to ask my college students, what is half of (hut) 8? Is it (Hut) 3?
