The theatre activities in Bombay and Calcutta had a strong influence from the Urdu heartland group and Taj was one of the pioneers of this group. In the post-Hashr days, Taj was considered the best playwright of the time. In the film titled "Anarkali," produced in 1953 and based on Imtiaz's plot, the ending was tragic, similar to the ending in the drama. Later the play formed the basis for the highly successful Indian feature film "Mughal-e-Azam", released in 1960. In this film produced by K. Asif, there was a twist to the story through a happy ending with Emperor Akbar finally being clement towards Anarkali. Though Imtiaz Ali Taj claimed that the film had no historical authenticity, he still gave snippets of historical evidence. In the preface to his book published in 1931 (designed to impress the middle class intelligentsia), he refers to Anarkali's existence during the historical period of Emperor Akbar (1556–1605) and his son Prince Salim (later Emperor Jahangir) as well as to the Persian couplet inscribed on the marble tomb in Agra dedicated to Anarkali by her lover Prince Salim who becomes Emperor Jahangir after the death of his father. The couplet reads ""Ta Kiyamat shukr geom kardgate khwesh ra, Aah garman bez benaam roo-e yare khwesh ra"", meaning: "Ah! could I behold the face of my love once more, I would give thanks to my God until the day of resurrection." In writing the love story of Anarkali, a love story with hidden meanings of the times, the author's intention, according to the critic Balwant Gargi, was "to represent tyrannical forms of patriarchal authority through the relationship between Crown Prince Saleem and his father 'Akbar the Great', which Taj portrays as domineering, and a 'complex father-son relationship' marked by 'filial love interlaced with hate'." In 1918, Taj also published a monthly magazine called the "Kahkashan" from the publishing firm of Darul Ishat which he owned. Another contemporary writer, Munshi Premchand, contributed stories to this magazine in Urdu. It so happened that an article which Premchand had submitted was on the same theme on which Taj was also writing a story. Then Taj decided to drop his article in favour of the one written by Premchand, who then expressed his regret but said that at least they both were on the same wavelength.
