While the set does indeed comprise three Grace Kelly movies, they don't make much of a collection. It's more of a duo than a trio. The movies are all watchable, but I have no idea why anyone would consider "The Bridges Of Toki-Ri" a Grace Kelly movie. Certainly she is in it, but only for about 10 minutes in the middle. The rest of the movie features William Holden in almost every scene, fighting in Korea, with sidekick Mickey Rooney. Grace is better known for "Rear Window", "Dial M For Murder", "High Noon", and so on. "The Bridges Of Toki-Ri" seems to be a bit of filler in the set. While it is a good effort for its time, and has many famous faces in it, it just isn't worthy of inclusion. Even the box write-up struggles to find anything to say about it.
Of the three movies, by far the best is "To Catch A Thief". The movie is very definitely classic Grace Kelly, and the DVD includes a few nice extras. There is an audio commentary, theatrical trailer, and four featurettes.
Each DVD is presented in a slimline plastic case, and all three are packaged in a nice solid cardboard sleeve.
Overall, it's a reasonable set spoiled by filler.
