A Graham Greene novel was the basic source for the British psychological melodrama Across the Bridge. Rod Steiger plays Carl Schaffner, a prominent financier who has absconded with company funds. A genius at improvisation, he plans to elude the authorities by murdering Paul Scarff (Bill Nagy) and assuming the dead mans identity. Upon arriving in Mexico, however, Schaffner learns to his chagrin that Scarff was himself an even more notorious fugitive from justice. ~ Hal Erickson, All Movie Guide
