Radnor, who starred on the hit television show "How I Met Your Mother," will joined by his playwriting teacher at the O'Neill, Donna Di Novelli and NTI artistic director Rachel Jett, who will moderate the conversation.

The discussion is the second installment of the three-part lecture series presented in conjunction with The Launchpad of the American Theater: The O’Neill Since 1964, a free multimedia exhibition on display in the Vincent Astor Gallery through Sept. 16. The series is held in commemoration of the 50th anniversary of the O’Neill theatre in Waterford, CT. 

Radnor attended the O’Neill’s National Theater Institute (NTI) in the spring of 1995. The 14-week, credit-earning training programs allows young theatre artists to gain experience in acting, playwriting, directing, voice and design.

Radnor wrote and directed the film "Liberal Arts," which premiered in 2012 starring himself, Elizabeth Olsen and Richard Jenkins. He will star in the Broadway premiere of Ayad Akhtar's Disgraced, which will begin previews Sept. 27 at the Lyceum Theatre. A Broadway opening has been set for Oct. 23.

The final discussion in the series, "The O’Neill: The Transformation of Modern American Theater with Jeffrey Sweet," will be presented  Aug. 7 at 6 PM. 

The O'Neill Theater Center, started in 1964 by Yale Drama student George C. White, has housed several actors and playwrights who came to the O'Neill as young arists such as Meryl Streep, Michael Douglas and playwrights Wendy Wasserstein and August Wilson.
