And never have the similarities between simians and humans been so amusingly and brilliantly captured as in Monkey Portraits by celebrity photographer Jill Greenberg.Jill has spent 15 years photographing everyone from Kelly Osbourne to Clint Eastwood, but has recently focused on photographing stars of a different sort. She has been photographing monkeys and apes, many of whom have appeared on movies or in television shows.
