The premise itself raises questions – a French actor portraying a Scotsman, a Scotsman as a Spaniard, and an American embodying a deranged Russian; how could that possibly work? Surprisingly, despite the unusual casting choices, it turns out to be a rather decent fantasy film. It introduces us to immortals contending with "the quickening," a phenomenon that has historically compelled them to battle (and sever the heads of) their own kind in pursuit of some final reward. Lambert embodies “Connor McLeod,” who arrives relatively late to this conflict and is banished from his Highland community after surviving injuries severe enough to kill an elephant. Fortunately, he meets and receives guidance from "Ramirez" (Connery), a centuries-old, cunning, and theatrical figure, preparing him to face the ‘Kurgen’ (Brown) – their most powerful (though perhaps not intelligent) warrior. The writing is undeniably poor, but the narrative itself proves entertaining. There's plenty of action, some truly impressive swordplay reminiscent of Errol Flynn, and even a touch of romance as contemporary science attempts to account for his extended lifespan. It significantly surpasses any of the films that followed it, and a memorable Queen soundtrack contributes to an enjoyable couple of hours filled with escapism, complemented by beautiful Scottish landscapes.
