227 is an American situation comedy that originally aired on NBC from September 14, 1985 until May 6, 1990. The series starred Marla Gibbs and was produced by Embassy Television from 1985 until 1988, then ELP Communications produced the series in its final two seasons (1988-1990).
Origins
The series was adapted from a play written in 1978 by Christine Houston about the lives of women in a predominantly black apartment building in 1950s Chicago. The setting of the series, however, was changed to present-day Washington, D.C.. The show was created as a starring vehicle for Marla Gibbs, who had become famous as the sassy maid, Florence Johnston, on The Jeffersons and had starred in Houston's play in Los Angeles. This role was similar in nature to that of tart-tongued Florence; Gibbs' character, housewife Mary Jenkins, loved a good gossip and often spoke what she thought, with sometimes not-so-favorable results.
Synopsis
227 followed the lives of people in a middle-class apartment building in Washington, D.C. At the center was Marla Gibbs, who portrayed Mary Jenkins, a nosy, tart-tongued housewife. Hal Williams played her husband, Lester, a construction worker, and Regina King played their studious 14-year-old daughter, Brenda; it was King's first significant acting role.
Also cast in 227 was Jackée Harry as the building's sexy vamp, Sandra Clark, who constantly bickered back and forth with Mary about their respective views on life. Helen Martin arrived to play Pearl Shay, a crotchety-but-kind busybody neighbor, who was always known for snooping. Pearl had a grandson named Calvin Dobbs, played by Curtis Baldwin, whom Brenda had a crush on and would finally date later in the series' run.
