Question: What role did Cate Blanchett play in the 1947 play written by playwright Tennessee Williams?
Context: The Notebook of Trigorin is a play by American playwright Tennessee Williams, adapted from Anton Chekhov's drama "The Seagull" (1895).  Williams based his adaptation primarily on Ann Dunnigan's 1960 translation. Cate Blanchett is an Australian actress who has extensively appeared in film and stage.  She made her stage debut in 1992 by playing Electra in the National Institute of Dramatic Art production of the same name.  She followed it with performances in Timothy Daly's "Kafka Dances" (1993) and the Sydney Theatre Company stage production of "Oleanna" (1993) opposite Geoffrey Rush.  Blanchett won the Sydney Theatre Critics Award for Best Newcomer for the former and Best Actress for the latter, making her the first person to win both awards at once.  She went on to perform several roles on stage, notably Susan Traherne in "Plenty" (1999), Hedda Gabler in "Hedda Gabler" (2004), Blanche DuBois in "A Streetcar Named Desire" (2009), Yelena in "Uncle Vanya" (2011) and Claire in "The Maids" (2013). Sweet Phoebe is an Australian play script by Michael Gow.  The 1994 world premiere production starring Cate Blanchett was by Sydney Theatre Company under the artistic direction of Wayne Harrison.  Other notable performances of the play include a 1995 stage production at the Croydon Warehouse also starring Cate Blanchett in her first stage performance in London. Memory play is a play in which a lead character narrates the events of the play, which are drawn from the character's memory.  The term was coined by playwright Tennessee Williams, describing his work "The Glass Menagerie".  In his production notes, Williams says, "Being a 'memory play', "The Glass Menagerie" can be presented with unusual freedom of convention."  In a widening of the definition, it has been argued that Harold Pinter's plays "Old Times", "No Man's Land" and "Betrayal" are memory plays, where "memory becomes a weapon".  Brian Friel's "Dancing at Lughnasa" is a late 20th-century example of the genre.

The festival is dedicated to the Pulitzer prize-winning American playwright Tennessee Williams.  Every year, it features several events related to the long career of that writer, as well as writing workshops, panel discussions, literary readings, stage performances, a book fair, music, writing contests, and other events related to American literature, poetry, drama, opera, film, photography, art, history, culture, and cooking.  The signature event is the "Stella and Stanley Shouting Contest" that closes the festival.

Tennessee Williams wrote "Spring Storm" when he was twenty-six years old, in 1937, while studying as an apprentice.  "Spring Storm" received poor reviews in Williams’s playwriting course, and it did not receive its first production until 1995 in Berkeley, California.  The European premiere took place at the Royal & Derngate Northampton on 15 October 2009, running alongside "Beyond the Horizon" by Eugene O'Neill.  Both productions subsequently transferred to the Royal National Theatre in 2010 to the Cottesloe Theatre.  Written and rewritten between 1937 and 1938, this full-length play depicts life and conflicted love in a small Mississippi Delta town during the Great Depression. A Streetcar Named Desire is a 1947 play written by American playwright Tennessee Williams that received the Pulitzer Prize for Drama in 1948.  The play opened on Broadway on December 3, 1947, and closed on December 17, 1949, in the Ethel Barrymore Theatre.  The Broadway production was directed by Elia Kazan and starred Jessica Tandy, Marlon Brando, Karl Malden, and Kim Hunter.  The London production opened in 1949 with Bonar Colleano, Vivien Leigh, and Renee Asherson and was directed by Laurence Olivier.  The drama "A Streetcar Named Desire" is often regarded as among the finest plays of the 20th century, and is considered by many to be Williams' greatest. The Magic Tower and Other One-Act Plays is a collection of 15 plays, seven of them previously unpublished, by American playwright Tennessee Williams.  Published by New Directions in New York City in 2011, Williams' scholar Thomas Keith edited the volume and provided the critical notes while playwright Terrence McNally, winner of four Tony Awards, wrote the foreword. The Traveling Companion and Other Plays is a collection of experimental plays written by American playwright Tennessee Williams and published by New Directions in New York City in 2008.  It is edited by Williams scholar Annette Saddik, who provides the introduction.  The majority of the plays are from the last decades of Williams's life, and are markedly different from those for which he is most known, departing from Southern locales, melodrama and naturalism, and showing the influence of Noh theatre and the Theatre of the Absurd.  The plays have never before been collected and some are previously unpublished.
