There was a very good Brit TV series (Mini series) about her 20 - 30 years ago. I'll see if I can track it down and let you know the name.
My recollection was that she was happy to maintain peaceful relations with the Romans after her husbands death but she and her two girls were raped by a Roman Commander and then all hell broke loose in the Iceni region :7
