Is it true?

Rating: 7/10 (12 January 2015)

I'm really waiting to watch that movie, I like Benedict Cumberbatch but I have doubts (again) if it's a true story.
You can find a lot info about the truth of enigma in the web:
( First part is from BBC and the second from Daily ) Bevore that I give you an example mentioned by Daily: No. 303 ("Kościuszko") Polish Fighter Squadron (Polish: 303 Dywizjon Myśliwski "Warszawski im. Tadeusza Kościuszki") was one of 16 Polish squadrons in the Royal Air Force (RAF) during the Second World War. It was the highest scoring of these 16 Polish-manned RAF squadrons during the Battle of Britain. Yet Polish troops - still under the command of Poland's independent government in exile - were forbidden from taking part in official VE Day celebrations due to Britain's wish to appease Stalin.
BBC 1...Prince Andrew handed over an Enigma machine taken from a captured Nazi submarine, as a "symbol of our gratitude". "The Enigma codes would not have been broken if it were not for the knowledge of Polish mathematicians," he was quoted as saying at the start of a two-day visit.
Mr Buzek said he was "greatly satisfied" that the UK officially recognised that Enigma was decoded by the Poles. Polish historians say three Polish mathematicians - Marian Rejewski, Jerzy Rozycki and Henryk Zygalski - broke the Enigma code in 1933. In July 1939, just before the war, Poland gave Britain and France replicas of the Enigma encoding machine, helping the Allies decipher secret Nazi messages. According to British accounts, British cryptographers cracked the code a year before war broke out. Mr Buzek asked Britain on Monday to change the Encyclopaedia Britannica entry on Enigma to credit the Poles for their role in breaking the system.
2. To many, the name Bletchley Park is synonymous with code-breaking glory by the British during World War Two. After all, it was there that Englishman Alan Turing and his team of mathematicians cracked the ciphers of the Nazis' Enigma machine - a feat credited with shortening the war by two years. But now, the Polish Government has launched a campaign to highlight the important - and overlooked - role played by its nation in solving the Enigma code. In 1932, a group of cryptologists from the Polish Cipher Bureau - Marian Rejewski, Jerzy Rozycki and Henryk Zygalski - discovered three ways of deciphering Enigma readings. Seven years later, just before war broke out, the Poles handed over their knowledge of the Enigma codes, as well as Polish-built replicas of the machines, to British and French Intelligence officers near Warsaw. The rest is history - but not the complete history, as far as Senator Piotr Zientarski is concerned. 'We have a duty to remind people just what the Polish cryptologists did,' he told the Daily Telegraph. The government official said that in recognition of the trio's efforts, the upper house of Poland's parliament has passed a resolution in their honour to 'restore justice'. The resolution reads: 'In both popular literature and official information, the public was told that the breaking of the Enigma codes was due to the work of the British Intelligence services to the complete omission of the work of Polish scientists.' The Germans, who had been using the technology since the late 1920s, believed the codes were impossible to crack. Using a complicated system of rotors, the machine would encode messages before sending them via Morse code to another machine. If the receiving machine had been programmed with the same settings - one of 158 million million million combinations - the message would be deciphered. However the team of cryptologists, linguists, scientists and data analysts at Bletchley, in Buckinghamshire, led by Londoner Turing, were able to break it. At its peak, the team was cracking 6,000 encrypted German Enigma messages every day - building on the principles set out by Rejewski, Rozycki and Zygalski. Jan Rulewski, a senator from the governing Civic Platform party, said: 'This resolution restores justice. Not only did the Western Allies marginalise the achievements of Polish cryptographers but the Soviets did the same. 'They were silent about the Polish contribution to saving the lives of hundreds of thousands of troops fighting on all fronts.' The film Enigma (made in 2001), starring Kate Winslet and set at Bletchley, has also upset the Poles - it not only downplays their contribution but also, the only Pole in the film is a traitor. The resentment adds to the wider feeling in the country that their contribution to the Allies' victory has been under-appreciated. Polish troops fought in North Africa, Italy and Normandy, and took part in the Battle for Berlin. In the Battle of Britain, Polish pilots had the highest kill rates. Yet Polish troops - still under the command of Poland's independent government in exile - were forbidden from taking part in official VE Day celebrations due to Britain's wish to appease Stalin.
