Reese Witherspoon will portray Elena Richardson, the Richardson matriarch who's also a Shaker Heights journalist. Even if you've only been minimally exposed to pop culture, you definitely know who Witherspoon is given that she's portrayed so many iconic characters such as Tracy Flick from Election and Elle Woods from Legally Blonde. If you can't wait for Little Fires Everywhere to come out, you can catch her as Madeline Mackenzie on Big Little Lies.
