When Dateline started premiering episodes about Pam Hupp back in 2013, they had no idea what they were in for. Over the next few years, they would keep coming back to Hupp as her name would continually be linked to several murders. She was finally arrested in 2016 for the murder of Louis Gumpenberger, In 2019, Dateline released a multi-episode podcast all about Hupp’s story. And they were right, there are some real strange things about Pam. NBC picked up the story now called The Thing About Pam starring Renée Zellweger, Josh Duhamel, and Judy Greer for a limited series that premiered on March 8, 2022. Here is a list of the characters to watch out for.

What is there to say about Pam Hupp? Well, we don’t want to give away the entire story, but she was accused of 2 (possibly 3) murders since 2011. She is a master of manipulation even to the point of swaying police and attorneys to believe her. Preying on people’s grief, Pam is skilled at twisting narratives and creating false scenarios so well that everyone trusts her at her word. It took investigators years to finally figure out what she was really up to, but the story of her journey is a fascinating one. It’s almost hard to watch how easily people can be fooled.

Zellweger’s breakout role came in 1996 in the film Jerry Maguire. Since then, she has starred in Me, Myself, & Irene, Bridget Jones’s Diary (and all its sequels), Chicago, Cinderella Man, and Miss Potter. Zellweger has won two Oscars, one for Best Actress for her portrayal of Judy Garland in 2019’s Judy and one for Supporting Actress in the film, Cold Mountain in 2003.

Joel Schwartz (Josh Duhamel)

As the defense attorney for Russ Faria, Joel Schwartz had his work cut out for him. One of the things about Pam is that it’s no easy task to prove she’s a liar. Thankfully, Schwartz never gave up as he was virtually Russ’s only hope.

Josh Duhamel got his start on All My Children back in 1999. Since then, he has starred in Las Vegas, Crossing Jordan, and Unsolved. He has also appeared in such films as Win a Date with Tad Hamilton!, When in Rome, and Love, Simon.

Russ Faria (Glenn Fleshler)

Poor Betsy. Recovering from cancer, trying to get her life back together and her only mistake was to trust the wrong person. Betsy is mostly shown through flashbacks in the series, for obvious reasons, but she is the catalyst to the overall story.

Louis Gumpenberger (Jeff Ryan Baker)

Pam’s first victim, or so they thought. Louis was an unsuspecting participant in a twisted fantasy that ended in murder. Gumpenberger had sustained impaired mental and physical capabilities after a devastating car accident in 2005, which made him an easy target for Pam’s scheme.

This is the first television role for Jeff Ryan Baker.

Janet (Suanne Spoke)

Betsy’s mom, Janet, doesn't know what to believe. She knows Russ would never hurt her daughter. But he is looking guiltier by the minute. At least that is what her trusted friend Pam keeps telling her. And why would she lie?

Minnie (Patricia French)

Minnie is Pam’s nosy neighbor. Does she really know Pam? Or is she just as in the dark as everyone else is? Minnie seems to keep popping up as Pam works her schemes almost as a voice whispering to Pam’s conscience. If only Pam had one.

Patricia French has appeared in True Detective, The Good Lord Bird, The Act, Halt and Catch Fire, and Ozark.
