Funny you should ask about the bee scene.  I had dinner with Norm Gary Monday
For those of you who don't know, Norm (from UC Davis) is a bee researcher
and consultant to Hollywood about bees.  The scene in question was filmed,
largely by standard film trickery.  The actress did not actually stick her
hand into the tree.  Norm did spend some time getting her used to bees by
putting newly hatched bees on her arm, etc.  But, mostly, it was "smoke
and mirrors".
