Pugh, Tison. "Seminal Semiotics and Pornographic Displeasures in David Lowery’s The Green Knight (2021)." Arthuriana, vol. 32 no. 3, Fall 2022, pp. 41-57. Project MUSE, doi:10.1353/art.2022.0030.
Abstract:
In The Green Knight, a cinematic adaptation of Sir Gawain and the Green Knight, director David Lowery includes a lingering shot of Gawain’s ejaculate. Lowery reframes this pornographic image as an alienating, rather than pleasureful, experience; in so doing, he probes similar themes concerning displeasure’s effects as the Gawain-Poet.
