The third installment in the Lester saga ,the fourth ("Le Vicomte De BRagelonne" feat. the iron mask) was never filmed ,because this one was not very commercially successful.
Roughly based on "Vingt Ans Après" ,"the return" was made sixteen years later ,with the same actors (Faye Dunaway ,Raquel Welch and Charlton Heston are not present ,their characters being all dead).Also Louis the Thirteenth is dead,Jean-Pierre Cassel who played his role,returns as Cyrano De Bergerac who comes at the most awkward moment.
The historical background is thin,although dealing with "La Fronde" ,a noble rebellion,and Mazarin's struggle to maintain the absolute monarchy ;and in spite of the musketeers,he was successful ,for the Sun King's reign only began with his death in 1661 ,when he was already 23.
Unlike in the book,it's a daughter (Justine De Winter) and not a son who wants to avenge her mother Milady.It's first surprising but becomes repetitive in the long run.It lacks some imagination:why not an affair with Raoul for instance?
The first movie of the saga remains the most successful:in this one,time has taken its toll,and what could have been another magnificent "Robin and Marion" ,a journey through the past tinged with nostalgia ,remains here a moderately entertaining swashbuckler.
