Mary Boehlert Katz, who assisted director Elia Kazan on the out-of-town production of Streetcar prior to its 1947 Broadway debut, donated the papers that detail Kazan's meticulous direction as well as a note by actor Hume Cronyn about his wife, Jessica Tandy's developing performance as Blanche DuBois.

Also included in the collection are technical notes and a complete copy of the revised rehearsal draft of the script.

"What's most interesting in the new materials is the picture of how detailed Kazan was in his directing. He corrected every gesture, the tone of voice, the timing," NYPL's Billy Rose Theatre Division curator Karen Nickeson said.

Variety shared highlights from the papers, which include the following (ungrammatical) notes from Kazan: "Blanche pat Stanley tummy to pacify him"; "Stella smooth out bed more"; "TENNESSEE: Don't you think speech of Blanche's too long about deaths at Belle Reve."

The original cast starred Marlon Brando, Tandy and Kim Hunter.

A Streetcar Named Desire will make its way back to Broadway in 2012, with Blair Underwood, Nicole Ari Parker and Daphne Rubin Vega among the cast. Emily Mann will direct the production that is produced by Stephen C. Byrd and Alia M. Jones of Front Row Productions.
