Why doesn't this hemi light cast shadows?

I would expect shadows from the girl, but nothing shows?girl sizing1.blend (7.48 MB)

Hemi lamps in Blender Internal don’t produce shadows:- https://docs.blender.org/manual/en/dev/render/blender_render/lighting/lamps/hemi.html

hemi lights are an old light trick to fake environment lights. no need to cast shadows.
