Coulson was once interviewed about her Log Lady role, and described her Margaret Lanterman character as the “only normal person on the show,” but qualified that she’s “had some trauma and bonded with this Ponderosa pine,” according to Variety.
Coulson first collaborated with Lynch on a short film in 1974 [The Amputee], then again on the 1977 film Eraserhead. Over a decade later, she would work with Lynch again on Twin Peaks as the enigmatic Log Lady, a role she reprised in [the 1992 movie] Twin Peaks: Fire Walk With Me and for the new Showtime revival of the series [now due in 2017], though there is no word as to how involved she was, as filming just started.
The noted stage actress also “reprised” her Log Lady role for the "Psych" Twin Peaks episode Dual Spires, though there she was called “Wood Woman.”
She is survived by her husband Marc Sirinsky and daughter Zoey. Source.
Nance died in South Pasadena, California on December 30, 1996 under mysterious circumstances. Nance told friends he had been beaten by a young man outside a Winchell's Donuts store in early hours of December 29.
Later that day, he lunched with friends Leo Bulgarini and Catherine Case. Nance had a visible "crescent shaped bruise" under his eye and when asked about it, he related to them the story about the fight. He soon went home, complaining of a headache. The injuries he received caused a subdural hematoma, resulting in his death the following morning. Nance died alone in his apartment. His body was discovered on the bathroom floor by Bulgarini. An autopsy revealed that the actor's blood alcohol level was .24 percent at the time of his death. A subsequent police investigation failed to find evidence of the alleged fight. Source.
Nance actually lived and died on Fair Oaks Avenue in South Pasadena. That is also the site of the old Historic Route 66, which was changed to SR 118, which used to extend past I-210 on Foothill Boulevard through Sunland, Tujunga, La Crescenta and La Cañada, then across the Arroyo Seco into Pasadena, California, where SR 118 ran on Lincoln Avenue and Fair Oaks Avenue, ending at Colorado Blvd (Alternate US 66). The original routing across the Arroyo Seco ran along La Cañada Verdugo Road (now Oak Grove Drive), which crossed the arroyo along the crest of Devil's Gate Dam.
