The Viking Queen (1967)

Taking much of its inspiration from the folk hero Boudicca, Hammer Studio's story is set in Britain during the Roman occupation. The political sea change that's forced upon the country's native tribes results in an armed uprising led by Queen Salina, played by Finnish fashion model Carita Järvinen.
Amid the calls to war a romance blossoms, failing to add as much emotional conflict as it ought to have done. The blend of politics, religion, state, and family concerns is equally as underwhelming at times. I'm guessing the makers were aware of the failings, so added some side-boob to spice it up.
The exterior scenes feel authentic, whereas many of the interior scenes have the usual stage-like Hammer theatrics, the kind that I adore.
