This 17-disc set of The Avengers offers everything that was in the 16-disc Emma Peel Mega-Set -- the complete two seasons' worth of episodes, one in black-and-wihte and the other in color, co-starring Diana Rigg as Emma Peel -- in the same transfers and from the same master sources. But it comes with one important addition: The bonus disc (Vol. 17), which includes three ultra-rare bonus features. The first and foremost of these is the presence of three ultra-rare Season One episodes of The Avengers (ironically, a season that didn't include Diana Rigg's Emma Peel, or any other female co-star), starring Ian Hendry and Patrick Macnee. The other major bonus feature is the documentary Avenging The Avengers, which includes interviews with the key cast members, giving the entire evolution of the series and the characters. There's also The New Avengers episode "The Tiger Awaits" (Part One), which included a cameo appearance by Rigg; the alternate American opening to Rigg's first season, a cleverly designed sequence placing Rigg and Patric Macnee in an oversized chessboard setting, while a voice-over explains who their characters are, for the benefit of US viewers unfamiliar with the series; and "The Strange Case of the Missing Corpse," a delightfully witty three-minute promotional sequence intended to promote the series' shift to color (again, for US audiences). Sad to say, the opening first season episode, "Hot Snow", only exists in a fragment containing the first half of the show, but that fragment and the other two episodes (only one of which features Macnee) do look very good, and the documentary is fascinating to watch, more than once. The bonus disc is loaded with material but the menu through which one accesses it is not well designed. It's very difficult to tell which option the menu is set on, and this reviewer found it impossible to get from "The Strange Case of the Missing Corpse" back to the main menu for another selection, requiring, instead, that we eject and restart the disc. Otherwise, the set is identical to its predecessor and a lot handier, taking up about a foot less shelf space.
