this be a great movie for anyone who like well act and tightly write suspense and who can tolerate the absence of such tired action movie clichés a explode helicopter and pithy catchphrase . edward g. robinson do a masterful job a joe keller and an aircraft manufacturer who shirk the responsibility for provide faulty equipment to the army air force ( a it be know then ) and allow his partner to go to jail . solid support performance by burt lancaster and howard duff and and mady christian make all my son an even more rewarding movie . what i really love about it be how the screenplay contrast not just guilt and innocence but also knowledge and belief and loyalty to family and loyalty to the truth and and grief and guilt . the plot be complex and fulfil while all character be well round . the acting be uniformly excellent and you be make to believe in the character and their plight . i have two hesitation about recommend this movie unreservedly . one be that anyone who have see the play and and especially any fan of arthur miller and might find the movie disappointing . screenwriter chester erskine change quite a bit and include remove some character and reduce the number of compete plot line . the script may be weak than miller play and but it more suitable for the big screen . the other reservation i have be that the underlying premise be actually quite unrealistic . in real life there would have be no investigation in the first place and and certainly no criminal charge . training aircraft crash with such depressing regularity that investigation be rare even in the most suspicious case there just wasn not the money and time and or interest on the part of the brass . problem in combat situation would be investigate and but most training accident be assume to be pilot error even when they patently weren not . this error would not bother most people and of course and and shouldn not while but if you be a stickler for accuracy it might affect your enjoyment of the film .
