In 1999, he spearheaded a charity campaign to raise funds for J. Madison Wright, the young girl who played his screen daughter on the television series Земля 2 (1994). Madison, then aged 15, had developed cardiomyopathy and was in dire need of a heart transplant, a very costly operation which exceeded her family's lifetime health insurance policy. Clancy offered to assist the Wrights in their plight. He also bought young Madison a laptop computer for Christmas in 1999. Tragically, Madison died seven years later, in July 2006, of a heart attack.
