The Lifetime TV movie, "Drew Peterson: Untouchable," aired Saturday and was watched by Petersen, currently in custody, and by members of the family of Stacy Petersen, Petersen's missing fourth wife, the Chicago Tribune reported.
Petersen, a retired Bollingbrook, Ill., police sergeant, is charged with killing his third wife Kathleen Savio, who was found dead in an empty bathtub in 2004.
Her death was initially ruled accidental but the case was reopened when Stacy Petersen disappeared in 2007.
Her family said they found the movie, starring Rob Lowe inaccurate, the Tribune said.
"It's so inaccurate, I had to laugh," Cassanda Cales, Stacy Petersen's sister, said. "It was so far-fetched and off-the-mark. I was sad about it before it aired, but it wasn't my sister's story."
Drew Petersen's lawyer confirmed his client watched the movie in the Will County jail.
"He thought it was hysterical," attorney Joel Brodsky said. "He chuckled at all of the inaccuracies and things that never happened."
Peterson remains in jail on $20 million bail while an appellate court considers the admissibility of hearsay evidence at trial, the Tribune said.
