Dick Lester's faithful two-part version of Dumas' adventure tale has truly imaginative action sequences, a cracklingly witty screenplay by George MacDonald Fraser, swashbuckling heroes (Oliver Reed, Frank Finlay), OTT villains (Faye Dunaway, Christopher Lee), a fantastic supporting cast (everyone from Charlton Heston to Spike Milligan) and a visibly huge budget. Wonderful stuff.
