In 2018, Greer first played a supporting role in Clint Eastwood's biographical drama "", as the mother of U.S. Air Force Staff Sergeant Spencer Stone. As part of an overall negative response, Tim Grierson of "ScreenDaily" lamented that Greer and co-star Jenna Fischer were "trapped playing supportive-parent clichés." Greer followed with Jim Loach's comedy-drama "Measure of a Man". Mick LaSalle of the "San Francisco Chronicle" felt she was "wasted" in the role of a mother who's teenage son is experiencing bullying. Greer co-starred in the biographical comedy "Driven", in which she played the wife of Jason Sudeikis' character, a man who gets busted by the FBI for trying to smuggle cocaine and subsequently becomes an informant. The film premiered at the Venice International Film Festival. Guy Lodge of "Variety" remarked that Greer was "reliably game in a princess-to-patsy part," while Boyd Van Hoeij of "The Hollywood Reporter" felt that Greer was "especially good" in a scene where she finds a wire on her husband.
