For the era it was made(late 1940's),BRUTE FORCE is surprisingly brutal and vicious in places,pre-dating similar antics from James Cagney two years later in WHITE HEAT. The majority of Hollywood prison movies seem to have riots in them and this is no exception,but BRUTE FORCE has arguably the most explosive of the lot,with tear gas,shootings,and killings galore. Mind you,with a warder as brutal as Hume Cronyn(who sadly died recently)in charge,it's no wonder.His psychological bulling of mild-mannered inmate Whit Bissell leads to the former's suicide,and savage beating of Sam Levene results in near death. The misery,waste,and isolation of prison life is well observed here,with fine performances all round,but especially from Cronyn and Jeff Corey,as a cringing,cowardly informer,both of whom incur the rage of the intense Burt Lancaster.
