fun and entertaining movie about wwii german spy ( julie andrew . ) fall in love with american pilot ( rock hudson ) and while try to get secret from him . for some reason this be attack by critic and shun by the public in 1970 i can not see why . it beautifully shot and have wonderful costume and interior and and excite aerial dogfight . also it have andrews do a strip tease ( strictly pg material ) and sing a beautiful song whistling in the dark . the movie do have problem . andrew and hudson do not get along during the shooting of this and it show . their love scene lack spark and they have zero sexual chemistry . still and they turn in ok performance . the film be a little long ( even in the 105 min director cut i saw ) and get way too dark and serious at the end . still and worth catching . try see the director cut . the other one run half an hour longer .
