This 1948 film is one of those very British movies made by Roy Boulting and follows the very young Richard Attenborough as the son of a NE London tobacconist who is sent to a famous public school ("Saintbury") as part of a social experiment. Very much of its time, the film is closer in ethos to Goodbye Mr Chips of 1939 than to the anarchic fantasyland of If (1969), the latter being, I think, closer to at least the psychological reality of my own schooldays of the early 1970's.
In a sense, one could look upon the film as showing Saintbury as a metaphor for England itself in 1948: still stuck in World War Two (the action starts during that war, despite having been made three years after the end of WW2); the idea that society should be opened up in terms of "equality of opportunity" but within the existing system rather than a radical remaking of that system; a one-nation idea which seems impossible now, with Britain (esp. England) deeply divided not only on the class lines of this film, but on racial, ethno-cultural and other bases.
The idea that the highest aim of any school student is to attend Oxford or (as in the film) Cambridge is still a pervasive idea today, as when Gordon Brown famously lambasted an Oxbridge college for rejecting a girl from the North East despite her having a number of (needless to say, these days, not worth much) "A" grades etc. Another reason the UK falls behind, this Oxbridge obsession.
The sentimentality of the ending is warming, yes, but also patently something which mirrors the way British people of 1948 wanted to think about their country: one which had come through the War honourably, to a decent society which was basically unchanged from 1939 but fairer...a world away from 2010...
Worth seeing.
