The Three Musketeers has been done to death over the years, with some very good and very bad films resulting. The two films presented here are, in my humble opinion, the best. If you're after some flashy hollywood production however, don't look here, go to the (truly terrible) 1996 effort starring Keifer Sutherland.
These films are relativley slow paced, filled with great performances from a variety of famous actors (Charlton Heston, Oliver Reed, Roy Kinnear and Spike Milligan to name but a very few - you really couldn't get a more varied bunch!) The slow pace allows for a good development of many minor characters and for the director's attention to detail to really draw you into the world of 17th century France.
The films include many elements, high drama, moral dilemmas and several lashings of humour. Oh, and plently of realism. None of your highly coreographed fight scenes that look more like dancing here, when brawls and sword fights come along they look very VERY realistic, and totally different to the usual hollywood attempt at such things.
In all, a very atmospheric and entertaining few hours, which will have you totally caught up in it. And for the price being asked here it's more than well worth it!
The only thing required now is the DVD release of the third film in the trilogy. This was filmed many years after these (which were originally made as one film but released as two shorter films by the distributor) and marked the last performance of Roy Kinnear.
