The titular character is played by Amanda Peet, who is known for her work in Something's Gotta Give, A Lot Like Love and Brockmire. As for her role in the USA Network anthology series, Peet tackles Betty Broderick, who is a convicted murderer for killing her ex-husband and his second wife. There was quite a bit of media attention surrounding this case as the deadly divorcée's first trial resulted in a hung jury and mistrial.
Eventually, she was retried and found guilty on two counts of second-degree murder. Betty is currently serving a 32-years-to-life sentence at the California Institution for Women.
Christian Slater is portraying Betty Broderick's ex-husband and victim, Daniel Broderick. It's safe to say that Betty and Dan had a messy divorce. While the medical student turned lawyer took custody of their children, as well as had an affair and married his much younger secretary, the blonde housewife broke several restraining orders and vandalized her ex's home.
During the high profile murder trial, Betty made claims that Dan had been abusive.
Slater isn't new to the USA Network as he won a Golden Globe for his work in Mr. Robot. He is also known for his work in Heathers, Interview with the Vampire, The Wife and so much more.
Rachel Keller, who is best known for her roles in Legion and Fargo, is playing mistress turned second wife Linda (née Kolkena) Broderick. At 21, former flight attendant Linda was hired by Dan to be his assistant. A year into her job, Betty accused Dan of having an affair with Linda. Once the marriage fell apart, Dan confirmed the affair and went on to marry Linda in April 1989.
Seven months into their marriage, the newlyweds were gunned down by Betty.
Riverdale and Once Upon a Time's Tiera Skovbye is also portraying Betty Broderick. Specifically, Tiera will play a young Betty as the latter's early days with Dan are examined.
The former flames met at the University of Notre Dame in 1965. By 1969, Betty and Dan were married and pregnant with their first child. They went on to have four kids together daughters Kim and Lee and sons Daniel and Rhett.
British-born actor Chris Mason, known for Pretty Little Liars: The Perfectionists and Vampire Academy, will also play Daniel Broderick, albeit a young Dan.
Dan was born in Pittsburgh, Pennsylvania and went on to get degrees from both Harvard Law School and Cornell School of Medicine. It's said Betty supported Dan by becoming the main provider during this time.
