essentially a undistinguished b movie that mysteriously be direct by one of the golden era major talent and fritz lang . even with the stellar name of lang and walter pidgeon and joan bennett and george sander and be prepare for a ludicrous storyline and bad acting and patently phony set and miscasting . for transparency sake and i have to admit i be an ardent non admirer of walter pidgeon and who be lucky to have find a niche at the artificial dream factory of mgm and and somehow work in secondary role and support greer garson and others . he be wildly miscast and act in a chipper and 30 ray milland madcap comedy tone and in a role where his life be in danger and and he be in hide . joan bennett cockney accent be excessive and but her lacquered hair and perfect makeup and classy outfit belie a street wise cockney slum girl . george sander be incapable of bad acting and but disappears after the preposterous opening find pidgeon somehow pretend to shoot adolph hitler . surprising for fritz lang be the unevenness of tone . i find the film waver uneasily between occasional moment of suspense thriller surround by light hearted comedic interplay . hitchcock totally reverse the ratio and use comic relief to occasionally pace the suspense . there be a reason this film be unknown . it do not serve or propel anybody career or reputation and and be forget because it a surprisingly bad film from such a pedigreed group .
