The Monthly Film Bulletin wrote: "It is easy to be antagonised by one's first impression of this film. Full of jerky movements and sudden cuts, it doesn't seem to hang together at all. One senses a kind of desperation, paralleled by technically uneven sound and lighting, and something outsize about the acting, particularly James Booth's, that a minimal plot can scarcely justify. Then an amused affection sets in. ... Frantic cutting may have spoilt the surface, but Joan Littlewood's first film remains fresh, vigorous and alive beneath. One hopes, that she will pursue her cinematic career in the same irrepressible spirit as that of the Cockneys she so remarkably depicts."
Variety wrote: "Joan Littlewood, who at the Theatre Workshop in London's East End, thumbed her nose cockily at most legit convention and brought a breath of fresh air into the general stuffiness, has now tackled her first film. Her lack of experience stands out like
Jimmy Durante's schnozz. At times it irritates. But ''Sparrows Can't Sing'' also gains by the sheer ebullience of Miss Littlewood's 'don't give a heck' attitude, at least in certain scenes. ...This is a highly colored and exaggerated version of the Cockney in which everybody is a larger than life character. But the camerawork, straying carelessly around the actual East End streets, is vital and vivid. And the whole effect is one of sheer exuberance."
Leslie Halliwell said: "Relentless caricatured cockney comedy melodrama, too self-conscious to be effective, and not at all likeable anyway."
The Radio Times Guide to Films gave the film 1/5 stars, writing: "You can't capture the sights and sounds of East End life simply by packing the cast with cockneys and touting a camera round the streets of Stepney. James Booth is eminently resistible as the sailor searching for wife Barbara Windsor and her bus-driving fancy man, George Sewell. Missing both social statement and fond characterisation, director Joan Littlewood has succeeded only in being patronising." == Accolades ==
