This thesis serves as documentation of my efforts to define accurately my creative process as an actor in creating the role of Masha in The Three Sisters by Anton Chekhov. This includes research, character analysis, rehearsal journal and an evaluation of my performance. The Three Sisters was produced by the University of New Orleans Department of Film, Theatre and Communication Arts in New Orleans, Louisiana. The play was performed in the Thrust Theatre of the Performing Arts Center at 8:00 pm on the evenings of April 19 through 21 and April 26 through 28, with one matinee at 2:30 pm on Sunday, April 29, 2007.
