“Mark Twain is a name not usually associated with Broadway, unless he is being portrayed by Hal Holbrook, the actor responsible for the one-man show ‘Mark Twain Tonight!’ But now a play by Twain called ‘Is He Dead?’ — adapted by David Ives — will receive its world premiere Nov. 29 on Broadway.” Written in 1898 and never performed, the play is about “a group of starving artists who stage the death of their mentor in an effort to increase the value of his work.”
