This is a superb collection of Esther Williams classics.
Although sold as a Region 1 boxed set, I found that five of the six discs of my copy (and I assume all other copies) are Region 0, and will play perfectly on an ordinary UK (or other European) DVD player. The sole Region 1 disc in the set is "Easy to Love", which is a shame as the Busby Berkeley choreographed water skiing sequence that forms the climax is unmissable. Fortunately, the film is available elsewhere as a Region 2 disc. Easy to Love
That's a Spanish DVD, but it's very easy to watch in English without subtitles, using the menu and a little common sense.
Add the Spanish DVD to this boxed set, and you have all six films readily playable on a Region 2 machine. That's absolutely fabulous!
