Renée Zellweger as Pam Hupp
A wig, facial prosthetics and a body suit helped Renée Zellweger transform into Pam Hupp. The daily makeover took "a couple hours," Zellweger revealed to E! "We started about four and we whittled it down to about two."
Josh Duhamel as Joel Schwartz
Josh Duhamel didn't need prosthetics—he has Joel's hair and suit down!
Glenn Fleshler as Russ Faria
Glenn Fleshler plays Russ Faria, Betsy's husband, and with the goatee, we can see the resemblance.
On Dec. 27, 2011, he found his wife covered in blood inside their home and assumed she had taken her own life. He was later arrested and convicted of her murder, but was acquitted of the crime in 2015.
Judy Greer as Leah Askey
Although Judy Greer doesn't exactly look like Leah Askey—the Lincoln County prosecutor who tried Russ Faria—they have the same-colored hair, matching lipstick and similar facial expressions.
Katy Mixon as Betsy Faria
Katy Mixon stars as Betsy Faria, who was found dead on Dec. 27, 2011 in her Missouri home.
From the curly hair to the eyes, Mixon bears a passing resemblance.
