Dreyfuss, 67, has been shooting the upcoming ABC miniseries, titled "Madoff," for several weeks. Production ends this month.
"Madoff," which is inspired by ABC News Chief Investigative Correspondent Brian Ross’ book "The Madoff Chronicles," documents the crimes of the financier behind the largest Ponzi scheme in history. In 2009, Madoff pleaded guilty to 11 federal felonies and is currently serving a 150-year sentence behind bars.
