i be surprise that some reviewer be a little disappointed with this great film . i find it to be hugely entertaining and with many surprising twist and turn . ok some of the accent be a bit questionable and for example while most of the lead actor play german officer use an authentic accent and whilst others in minor role do not bother with one . the only two piece of cast i have a slight problem with be use quintessential scotsman gordon jackson a omar sharif colleague and an american unknown actor a the german news reporter . sharif himself be excellent a the dogged and principled investigator and but it be otoole who dominate the film . he be simply chill and quite believable a the withdrawn and intensely private and psychotic butcher of warsaw . well worth watch .
