Borgnine is a Viking leader that rapes an English queen during a raid and kills her husband. The queen has a child as a result but sends him away to be raised where he will be safe. Twenty years later, the son, played by Curtis, is taken as a slave by Borgnine's son, played by Douglas, who is, unbeknownst to him, his half-brother. The Vikings' was filmed in Technirama, an early widescreen process. The quality of the transfer is suprisingly good.
Colors are a bit faded but still good.
Contrast and brightness are very good, thus helping out the colors a little. The image is clear and sharp most of the time with only occasional signs of age. Overall, this film looks better than it has a right to. The soundtrack is mono and in about the condition one would expect for material of this age. The dialog is fairly clear but there is a bit of harshness that will probably keep the volume control in check.
