[separator headline=”h3″ title=”Letha Nall”]

Lethia Nall is a native Louisvillian and an alumni of Walden Theatre (1985-1991). She was lucky enough to be taught and mentored by the unique genius that was Nancy Niles Sexton and is still working on “Early is on time, on time is late!” Marc Antony in Julius Caesar and Abigail in The Crucible are favorites. Later she studied the ballads of John Jacob Niles and Appalachian dulcimer under Ms. Sexton, work she continues to this day. Nall lived and worked as an actor in New York City for 11 years. The premiere of Tom Stoppard’s Indian Ink at SOHO Rep and As You Like It at the Public Theatre are highlights. Films: Summertime in New York; A Decent Arrangement (shot in India). TV: Law & Order, Rescue Me. A graduate of Vassar College with a major in both Drama and Anthropology and also of BADA in London. She is so very grateful to be a part of the work here tonight and to be back on stage with her talented friend from so many moons ago, the rapturous Ms. Mudd.

[separator headline=”h3″ title=”Neill Robertson”]

Neill is a proud alum of the Walden Theatre Conservatory program at the Commonwealth Theatre Center (2003). Upon graduating from the program, Neill attended the American Music and Dramatic Academy in New York City, where he graduated in 2005. Neill moved back to Louisville in 2010, and he has been seen on stage all over the city. Recent credits include Dracula at Actors Theatre of Louisville (Renfield), Hamlet with Stage One (Horatio/Player Queen), Richard II with Kentucky Shakespeare (King Richard), Misalliance with the Professional Co. at Commonwealth Theatre Center (Bunny), the title role in Hedwig and the Angry Inch with Pandora Productions, and The Language Archive with Theatre [502] (Resten). Without the technique, discipline, and passion that was instilled in him at such a formative age by the instructors at Walden Theatre, Neill would not be the full time, professional actor that he is today. As Nancy Sexton would say, “Focus- Concentrate- Listen- Think- React.”- words of wisdom to carry with you throughout your entire life.
