Although the film provided the play a larger mainstream audience, the huge expectations and powerful performances in the play posed a challenge for Kazan.
The film’s audience had to depend on the director’s perspective of the play to gain information about it. One problem is that Kazan adapted the film from the play which is itself an interpretation of the original text instead of making an elaborate study of the text. Although the study of characters and plot presented by Kazan can make an interesting topic, those who have a preconceived idea about the same from the play will have to unlearn those ideas. This is because Kazan added his own interpretation of the characters and plot in his film which is quite different from the play.
One problem that can arise with an adaption from a play is that the creator of the player himself may not have been truly faithful to the original text. Keeping this in mind, it has been noticed that the sexual preference of Blanche’s husband, i.e. homosexuality is omitted in the film version while the same is included in the play. While in the play the husband commits suicide after his homosexuality is revealed, in the film Blanche admits that her behavior has driven him towards suicide. There can be several reasons for this, for instance, the censor board might obstruct liberal representation of the text or Kazan’s perspective about the character may have been different.
Another difference between the play and the film version is the location used. In the play, the entire story has been presented within the confines of Kowalski apartment. On the other hand, in the film scenes have been shot in various locations that have either been briefly mentioned in the play or have been omitted totally like the railway station, bowling alley, pier of a dance casino, machine factory etc.
