Wow ! I really enjoyed it !
I noticed a cameo appearance of Kim Syggurdsen as the white-bearded Vikingr captain, lying dead on the ground while another Vikingr closed his eyes, ( though he was still breating ). He also appeared as one of the two Saxon soldier's elderly father, killed at their Sussex village.
This man ( Siggurdsen ) is the founder of Regia Anglorum, the British reenactment society who built the longhouse I fell in love with and whose pictures I posted in the forum. They often do film and TV work, so I guess if you pay attention, you might recognize them from time to time.
Thank you Cynan for posting this ! ( please note the absence of "Sir", as per your request ... )
