Like Jean Vigo‘s L'Atalante,the key scene of the story is a boat,few performers experienced a episode of their life on it,both film seeks to express its thoughts about marriage and go to different wharf. In the former one,which begins with a wedding ceremony of the captain,the whole atmosphere is cozy and even sort of humorous.Among the routine of everyday life,the bride find a new world and,after a short time on the bank, she returns eventually. In the later film,the boy have a short journey with a middle class couple,whom are under a sensitive period of their marriage.He is a invader,poor,ambitious and sentimental,on the contrary,the husband is sophisticated,veteran and arbitrary. Two films both employ metaphors to hint something,for example the boat symbolize the floating life,the boy and the bride is the stranger and fresh confronted with a adventure. As a light comedy,Jean Vigo utilize various of witty elements to set up his aesthetic style,the weird crew including a blunt boy and a old bachelor and the naked women tattoos,Chinese fun which in some degree construct a exotic and gray world. Roman Polanski's story has a inner tension,the director harness it perfectly.The boy is obscuring his swimming skill,he is in a dilemma which he attributes to flee,however he acquires some happy time on the boat the same time,he feel freedom and even love. In the end,the boy goes away lonely and the car stops with a hesitating couple.Maybe the director wants to deliver that people are always vulnerable when they face a new direction just like a drowning knife whose weight and sharpness only hasten its sinking.
