CAST: The former Dr. Doogie Howser, Neil Patrick Harris, now 30, will play JFK’s killer, Lee Harvey Oswald, in the long-awaited first Broadway production of composer-lyricist Stephen Sondheim‘s controversial musical “Assassins,” reports Variety.

A fall 2001 production of the show was canceled after the Sept. 11 terrorist attacks.
