In the Mood for Love 花樣年華 (2000)

“He remembers those vanished years. As though looking through a dusty window pane, the past is something he could see, but not touch. And everything he sees is blurred and indistinct.”
“他記得那些逝去的年華。就好像透過一扇蒙了塵的窗戶看出去，他能看到過去，卻無法觸及。他看到的一切都模糊不清。”

The quotation from writer Liu Yi-Chang’s stream-of-consciousness novella, Intersection, loosely inspired Wong Kar-wai into capturing the tentative affair between two would-be lovers who cross paths briefly before parting forever.
劉以鬯的意識流小說《對倒》中的這段話給王家衛帶來一點靈感，讓他得以捕捉到生活有短暫交集、最終又各奔東西的兩個人之間可能產生的那一點情愫。

The year is 1962, and as next-door neighbors living in a crowded apartment complex, Mr Chow (Tony Leung) and Mrs Chan (Maggie Cheung in a cheongsam showcase) gradually discover their spouses are having a clandestine affair. Alternately finding solace by spending time with each other, and masochistically toying with the other’s emotions by rehearsing imaginary breakups, the two soon consummate their mutual longing by role-playing as their cheating partners.
故事發生在1962年，周先生（梁朝偉飾）和陳太太（張曼玉飾，整片上演旗袍秀）兩家是某棟擁擠公寓樓里的鄰居。兩人都發現自己的另一半在外面有私情。于是，兩人經常在一起互相安慰，還上演假裝分手的虐心橋段。后來，兩人通過扮演各自出軌的伴侶滿足了對彼此的渴望。
