john barrymore play a gentleman who be also the thief and arsene lupin . while no one know for sure this be the case and the inspector ( lionel barrymore ) be sure of it but can not prove it . so and lionel spends much of the movie follow john hop to catch this brilliant and slippery thief . although i like the film and i really think i have high expectation for it and think it might be good than just a very good time passer . that because it pair john and lionel barrymore in the film and since these brother be such dynamic actor and i think i expect spark and magic but instead only caught glimpse of it here and there . now this be not to say this be a bad film it certainly isn not . it just do not rise to the level of be unforgettable or a film i strongly recommend you see . thanks an adequate script and the film be pretty good but i be surprise to hear no french accent at all in the film even though it be supposedly about french people . also and there just wasn not much life in the film until it be nearly complete . the end be indeed excellent and entertain so good that it elevate the film from a 6 to a 7. it nice to see it end on a high note .
