Delphinium: A Childhood Portrait of Derek Jarman (2009) Delphinium is a stylized and lyrical coming-of-age portrait of Derek Jarman's artistic, sexual, and political awakening in post-War England. Part biographical narrative, part experimental collage, part personal meditation on the most controversial and important modern British artist and activist, the film finds in Jarman's childhood the stirrings of creative and individual epiphany that inspired a remarkable life.
