633 Squadron

633 Squadron is a 1964 British film, which depicts the exploits of a fictional Second World War British fighterbomber squadron and stars Cliff Robertson, George Chakiris and Maria Perschy. The plot was based on a novel of the same name by Frederick E. Smith, published in 1956, which itself drew on several real Royal Air Force operations. The film was directed by Walter Grauman and produced by Cecil F. Ford for the second film of Mirisch Productions UK subsidiary Mirisch Films for United Artists. 633 Squadron was the first aviation film to be shot in colour and Panavision widescreen.

Still worried, Air ViceMarshal Davis decides to move up the attack to the next day. However, the resistance fighters are ambushed and killed, leaving the defences still intact. Although Grant is given the option of aborting, he decides to press on. The factory is destroyed at the cost of the entire squadron, though a few crews are able to ditch in the fjord. Grant crashlands but a local man helps Grants navigator, Flying Officer Hoppy Hopkinson, pull the wounded wing commander from the burning wreckage. Back in Britain, Davis tells a fellow officer who is aghast at the losses, You cant kill a squadron.Authentic period aircraft were used instead of models or special effects to create many of the aerial sequences. In part, this was because 633 Squadron was the first film shot in colour in Panavision widescreen format, a choice that made the use of archival film a common expedient and costsaving measure in previous films problematic. However, some aerial sequences were created using models and these are very obvious due to the unrealistic ways the models move. ........
