There, Mark’s natural empathy and easygoing style helped open doors to hundreds of celebrity interviews: from multiple sit-downs with Michael J. Fox and Christopher Reeve, to following Rosie O’Donnell and Robert Downey Jr. through the ups and painful downs of their careers; from sitting down with the Olsen Twins on their eighteenth birthday celebration, to revealing Al Roker’s shocking weight loss secret.
