Martin is a hardened, cynical career criminal, while Stannard is a naïve, rather dull-witted youth who has never previously been in trouble with the law, maintains his innocence of the rape of which he has been accused and is terrified by the prospect of prison.

Martin steals an army corporal's uniform and passes Stannard off as a deserter in his charge being returned to face a military tribunal, which explains why they are handcuffed together.

The escape location has been chosen by Martin for its proximity to a garage run by his mistress Nora Lawrence (Jane Hylton), who provides the pair with overnight shelter.

Rather than give himself up, Martin makes a final doomed attempt to escape through a warning-signed minefield, watched by police, reporters, his wife, mistress and a crowd of sensation-seeking gawkers.

Gainsborough had meant to make another film that month called Roses Her Pillow, but production on that was postponed when Margaret Lockwood refused to star and Sydney Box could not find anyone he felt was suitable to replace her, so he brought forward Double Pursuit on the studio's schedule.

[7] My Brother's Keeper's exterior location sequences were filmed in the Buckinghamshire/Oxfordshire border area, including scenes shot at the now abandoned Aston Rowant railway station.

The film's main weakness is cited as the interpolation of a pseudo-comic and largely irrelevant subplot involving a newspaper reporter trying to cover the story while on honeymoon in the area, although this 'framing device' could also be likened to the 'comic relief' interludes found in Shakespearian – and other – tragedies which somehow both enhance and make bearable the serious 'meat' of the drama.
