Isadora, the 1968 film by Karel Reisz, is as over the top as its larger-than-life subject, free-spirited terpsichorean Isadora Duncan. Though fairly traditional in format, the often intense emotional tone borders on the hysteria of early Ken Russell biopics. (Russell, in fact, did his own Duncan film.) Music and dance prevail, with some wonderful set pieces. Vanessa Redgrave, at the height of her beauty, gives the very definition of a bravura performance as the mercurial Duncan, portraying her from youth through her untimely demise at age fifty. Inspiring and tragic, Isadora may play fast and loose with the facts, but it's tremendously entertaining in a way that movies seldom are anymore.
