Greer's last feature film was a prominent role as the 108-year-old version of the character played by Tom Hanks in 1999's "The Green Mile", 61 years after Greer was an extra in the 1938 film "Jesse James". Greer's last television performance was in a 2003 episode of "Lizzie McGuire". Most of Greer's nearly 100 movie roles and appearances in nearly 600 television episodes of various series had been in supporting roles, but he told the "Albany Times Union" in 2000 that "every character actor, in their own little sphere, is the lead".
