Sinise's portrayal of Wallace is astonishing, but I was most impressed by Mare Winningham's perfect performance as Lurleen. Like any Southerner, I'm more than accustomed to actors' ham-handed, mangled versions of Southern intonation and dialect, but Winningham was amazing. She BECAME Lurleen Wallace. At times you can be fooled into thinking that Winningham is lip-synching over an archival recording of Lurleen's speeches. Everything about her performance is superb.
