While Bernie Madoff is the subject of the upcoming documentary, Chasing Madoff, the real star is whistle blower Harry Markopolos.
In the new trailer for the film, provided by Yahoo!, clips of Markopolos intertwine with headlines, graphics, archival footage of Madoff and sound effects, including that of a gun.
The documentary, produced by Cohen Media Group, is based on Markopolos' bestselling 2010 book, No One Would Listen: A True Financial Thriller, published in 2010.
Markopolos, 54, is of course famous for leading a team of investigators over a ten-year period in the eventual takedown of Madoff and his Ponzi scheme.
In June 2009, Madoff was sentenced to 150 years in prison. Madoff is currently at a medium-security Federal Correctional Institution in Butner, N. C.
Chasing Madoff, directed by Canadian filmmaker Jeff Prosserman, also features interviews with Frank Casey, Neil Chelo and Gaytri Kachroo.
The documentary is the second film project to surface since the Madoff scandal.
In May, multiple reports confirmed that Robert DeNiro had signed on to star as Madoff in an upcoming HBO film, but no new information has been released since.
Chasing Madoff: Unfortunately Based on a True Story arrives in select theaters on Aug. 26.
