Annie - the original 1977 Annie - was not a children's musical. The show's rep has been destroyed and diluted by the 1982 film, the 1999 TV movie, the 20th anniversary revival and the countless tours and amateur productions. That original production was a fantastic entertainment, with a great cast and a gorgeous physical production. It appealed to everyone - not just children and families - which is why it ran six years and survived the move to three other theatres.
Lapine is an interesting character - he began his career as a graphic artist, so his shows usually look great. It makes me think it won't be one of those cheap-looking Annies we've been seeing. And he has a sure hand with comedy. He's an unexpected choice, to be sure, but it's more interesting to me than several of the musical directors out there, especially some of the musical revival stalwarts like Kathleen Marshall or Walter Bobbie. I'm curious to see what he comes up with.
Begin at the beginning and go on till you come to the end: then stop.
