It isn’t quite up to the standard set by the previous installment, yet Richard Lester brought everyone back together again for another lively adaptation of Alexandre Dumas' tales of bravery during the reign of King Louis XIII (Jean-Pierre Cassel). This time around, after a close call in the last film, Cardinal Richelieu (Charlton Heston) is even more determined to uncover the truth about the Queen (Geraldine Chaplin) and her affair with Buckingham (Simon Ward), so he’s enlisted "Rochefort" (Christopher Lee) and the sinister "Lady De Winter" (Faye Dunaway) to extract information from dressmaker "Constance" (Raquel Welch). Simultaneously, the enthusiastic "D'Artagnan"—a rather thin Michael York—is also after her, with help from his companions "Porthos" (Frank Finlay), "Aramis" (Richard Chamberlain), and "Athos" (Oliver Reed), leading to a series of events as they try to stop the Cardinal’s schemes and rescue “Constance” from the wicked “Milady”. The film is vibrant and full of action, with notable contributions from the supporting cast—particularly Reed, who seems completely comfortable in his role and likely enjoying some genuine vin rouge. Roy Kinnear reacts with comic disbelief, and there's a rather spectacular game of cricket that’s more exciting than any I've witnessed at Lord’s! Dunaway is excellent as the scheming woman, and Welch also does well portraying the innocent young seamstress who barely fits into her own gowns. Heston doesn’t appear enough to really make his presence felt, but Christopher Lee performs admirably—his line about a firing squad “perhaps I'll die of old age” did elicit a chuckle—as this pleasant historical drama approaches its rather suitable, though somewhat underwhelming, conclusion. These are worthwhile films for those who appreciate action comedies, and they’re still worth seeing fifty years on.
