Three added to Danes's 'Grandin'

Julia Ormond, David Strathairn and Catherine O'Hara have joined the cast of HBO's Temple Grandin biopic.

Claire Danes is already on board to star in the lead role of an autistic woman who becomes one of the top scientists in humane livestock handling.

Ormond will play Grandin's mother, Strathairn her university science teacher and O'Hara her aunt.

The untitled movie begins filming this month in Texas under the direction of Bodyguard helmer Mick Jackson. Merritt Johnson and Christopher Monger wrote the screenplay.
