This is the critically acclaimed collaboration for the screen by choreographer Merce Cunningham, composer John Cage, and filmmaker Elliot Caplan.  The first half features BBC's documentary: interviews with Cunningham, Cage and members of the company, as well as scenes from rehearsals in New York and London take the viewer through the complexities - and exhilaration - of bringing new dance to television.  The second half features Points in Space performed by Cunningham and the Merce Cunningham Dance Company.
