Héctor Canziani was an Argentine poet, screenwriter and film director who worked in Argentine cinema in the 1940s and 1950s. Although his work was most abundant in screenwriting and poetry after his brief film career, he is best known for his directorship and production of the 1950 tango dancing film Al Compás de tu Mentira based on a play by Oscar Wilde.
Canziani was a Poet who had a brief but successful career in the film industry.
it is definitely correct that he had a brief but successful career in film because he is best known for his work on a film, but as stated, his work in the field was brief. I think it is difficult for the system to recognize becuase while he clearly was successful, that is not a word used in the statement.
