this is an excellent film of the mid Ealing period Critchton's tight direction and Bridgewaters music intertwined with each characters role in the film is truly marvellous! as time has passed all but one of the cast members have died, with the exception of Giselle Preville who plays Julie the wireless operator. i have watched this film many times and cannot get enough of the opening score by Bridgewater. i throughly recommend this film as an all time Ealing great, although many Ealing aficionados will probably not agree, as it received a very Luke warm reception in 1948 possibly due to public tiredness of all things to do with war.
