Plummer's work in features has ranged from supporting roles to leads. His early work included playing a kid from Harlem in "Who's That Girl?" (1987), the young thug High Top in Dennis Hopper's "Colors" (1988) and a busboy with dreams in Garry Marshall's "Frankie & Johnnie" (1991). He got his biggest break in Steve Anderson's "South Central" (1992), as Bobby Johnson, the ex-con father who does not want his son following his example. Plummer also acted as a creative consultant on the film. But few feature leads followed. He appeared in the Hughes Brothers' "Menace II Society" (1993) and as the motorist whose fancy sports car is borrowed by Keanu Reeves in "Speed" (1994). Plummer went on to portray James Smith, the choreographer more interested in bedding women in "Showgirls" and a political activist-cum-rapper in "Strange Days" (both 1995). He appears as a TV cameraman with Michelle Pfeiffer and Robert Redford in "Up Close and Personal", and in support of Robert Pastorelli in "The Asphalt Quartet", of Tom Berenger, Ernie Hudson and Diane Venora in "The Substitute", and of Jeff Fahey in "Waiting for the Moon" (all 1996).
