Like most enthusiasts of 'the Prisoner,' I have watched 'Many Happy Returns' time and time again, and time and time again I've been pleasantly surprised that the series still has the power to produce something new to be seen. Take Number 6 at sea aboard his raft, it wasn't until a recent screening of this episode that my wife suddenly said "The raft appears to be going backwards!" So we rewound the video tape and watched again. And yes it's true, that although the sail is full of wind, the raft itself is going backwards! It must be a very strong tide at that point, either that or the raft is under tow!
