Abell worked as a stagehand and a costume designer in Paris before he got his big break as a playwright in 1935 with Melodien, der blev vœk 1935,, which is a playful comedy about spiritual disorientation in a technological society; it is also expressionistic in that it utilizes non-verbal and unrealistic elements, undoubtedly inspired by ballet. The first production of this play was in 1935 in Copenhagen followed by a production a year later in London by the Arts Theatre. In this play Abell describes the life of the "white-collar worker" limited by old-fashioned conventions, and it is a fantasy about the mental emancipation of "the little man". A young, disrespectful attitude together with both lyric and imaginative dialogue has let it remain his most popular work. Some of its song lines have become classics. Both before and during the Nazi occupation of Denmark, Abell used his plays to protest the loss of freedom. Themes in these plays explore freedom and escapism as self-annihilation. These works include Anna Sophie Hedvig, a defence of violence as a necessary means against tyranny and a criticism of passive humanism, beyond any doubt inspired by the Spanish Civil War, and Dronning gaar igen. Abell spent much of his time during the occupation in hiding due to his anti-Nazi activism. Silkeborg expresses criticism of both Danish passivity and acceptance of the German occupation. Following the war many of his plays took on complex mystical elements. These plays include Dage paa en sky, Den blå pekingeser, Kameliadamen and Skriget. The much debated Dage paa en Sky both takes place among the Olympic mythological goddesses and in the brain of a suicidal scientist, it warns against the atomic war, and accuses scientists of prostituting themselves to the rulers. The even more complex Den blå pekingeser also takes place in the head of a man, while his former love is threatened by death. Again the message is to break one's isolation and to accept life. Abell died in Copenhagen. Hailed in his prime as a fresh and humorous reformer, critic and teaser of Danish theatre and later respected for his anti-fascist attitudes. After the war Abell was accused of being a fellow traveller and also criticised for being too complicated and strained. This together with his growing disappointments with the left wing partly led to isolation. However he is probably still regarded as the most important new-thinker of Danish drama of the inter-war period. In European dramatic literature he has been compared to French authors such as Giraudoux and Anouilh. He also was a song writer of revues, and he wrote film scripts. He became a member of the Danish Academy in 1960.
