Directing on Broadway at 20, at least according to ibdb, although some of those early productions might not strictly be considered to have been Broadway as we currently understand it. Certainly that Macbeth probably would not now be considered Broadway (and I don't think it was considered Broadway back then), but in those days it was all very amorphous. Still, no matter how you look at it, he was probably the youngest, unless there was someone even younger in the 19th century.
Btw, Eva Le Gallienne both directed and played Hilde Wangel in The Master Builder when she was 26, although around 4 months closer to 27 than Leveaux was at the time of that Moon. And then there's Cohan, mentioned by larry13 below. |
