How do you turn a decent cartoon about African wildlife into a lame Broadway musical? 1) Puzzle carefully about the problem of costumes and sets. Pour millions of dollars and hours of mental energy into making your actors look like lions, hyenas, elephants, wildebeests, giraffes, and birds. Solve the problem brilliantly. Hire Julie Taymor to design the magnificent costumes and masks (and to direct the show). Hire Garth Fagan to choreograph elegant, exciting, Afro-Caribbean dance routines. Make sure Donald Holder lights the stage with an eloquent feeling for African distances and sunshine. In general make the show a visual feast. Then, 2) squint in confusion at the script, and 3) carve it up to make room for appalling songs by Tim Rice and Elton John. You'll have a profitable bunch of nonsense with more than one God-soaked number that sounds indistinguishable from bad Whitney Houston. The only cast member who can transcend this mess and give a stirring performance is Thandazile Soni, as Rafiki the monkey shaman, who gets to sing songs like "Nants' Ingonyama," by Lebo M, and other African chants originated by Tsidii Le Loka on Broadway. Bob Bouchard is also funny as Pumbaa the warthog, and Derek Smith plays a perfectly arrogant, sinister Scar, the pretender lion king. Otherwise the show is forced and childish. Adults looking for good theater will be happier when the performers dance instead of trying to act.
