Worth watching (many times) if just for the 1950s elegance of northern Italy and of the cars (such glorious sounds). The young boy's comic book style plot, scenes and dialogue only add to the charm. The actors are all such a pleasure to watch, also due to their wardrobe styling, not just their acting and good looks. Reminiscent to To Catch A Thief, which was romance with a bit of "adventure", Checkpoint is adventure with a bit of "romance".
