Trailer for A Number.
In a world where human cloning has become a reality, two genetically identical men confront their father in separate, chilling encounters, each looking for explanations into their shared past - and receiving disturbing answers that neither may want to hear. HBO Films presents Emmy Award®-winner Tom Wilkinson and Rhys Ifans in this shattering meditation on human identity as it examines the issues of human cloning and nature vs. nurture. Adapted by acclaimed playwright Caryl Churchill from her original stage play of the same name.
