自公元前460年左右,希臘戲劇舞臺上最早使用門作為布景開始,便徹底改變了悲劇的節奏,可因門所創造的幻覺使各個場景交切,顯示出幾個時間和空間同步進行的效果,門的存在可以用于隱藏亦能用作揭秘,其創造出的想像世界意蘊豐富。劇場中的門代表著臺上世界與臺下世界的通道,演員自門"上場",他們的身份由普通人得以轉化為戲劇角色,電視情景劇中"未上鎖的門"也起到了類似的作用。幾乎所有的舞臺、電影、電視劇的房間都設置了門,然而戲劇舞臺上的門卻與電視中的門有著千差萬別。門打開,信息便涌入;門關上,信息便終止流動。門檻的魔幻色彩具有強烈的象征意義,保留了格外鄭重的儀式感,沒有了門,就沒有了宏偉的下場,因此也就沒有真正的結尾。

Back to 460 B.C.,a door was first used on the Greek stage,fundamentally altering the rhythm of the tragedy.The door and the illusion it created allowed an intercutting of scenes that had the effect of telescoping time and space.The door hides,and the door reveals.The sense of imaginary worlds it creates is very rich.In the theatre doors represent the passage between the onstage and offstage worlds.The actors enter the stage through a door and they are transformed from ordinary people to characters.The apartment door always unlocked in sitcoms functions something similar.Our stages,movies,and television shows depict rooms with doors,but the doors we see on television are different from those we have encountered onstage.The doorway opens and information flows in;it closes and the information flow ceases.Thresholds carry magical significance that maintains the sense of mortality.Without doors,there can be no grand exit and thus there is no finality.
