If you’re wondering where you might’ve seen Anne-Marie Johnson before, it may be tough to pin down. That’s because she’s amassed more than 100 screen credits over the past few decades, and appeared in some of the biggest shows on the air over that span. Johnson’s early credits include ’80s staples like “Different Strokes,” “Hill Street Blues,” and “Hunter.” But in 1985, Johnson booked the first of her signature roles, playing Nadine Hudson Thompson in all three seasons of “What’s Happening Now!” 

When that series ended in 1988, Johnson would land arguably the biggest role of her career, playing Althea Gibbs in the small screen adaptation of “In the Heat of the Night.” She’d play that role for the bulk of the series’ eight-season run, and earn raves for her soulful work as the iron-willed wife of small-town Chief of Detectives Virgil Gibbs (Howard E. Rollins Jr.).

Johnson would follow that dramatic gig by joining the cast of Fox’s beloved ’90s sketch comedy series “In Living Color,” and go on to appear in other era hits like “Melrose Place,” “ER,” “Mad About You,” “The X-Files,” and “Ally McBeal,” among others. Johnson has continued to book work on high-profile projects since. She’s also been a regular in the “NCIS” realm, appearing in 18 episodes of the series’ predecessor “JAG” as Representative Bobbi Latham, later turning up as Doctor Adams in two episodes of “NCIS: Los Angeles.” And with four separate “NCIS” characters under her belt, one has to think Johnson’s presence in that universe might cause some serious continuity issues if creatives aren’t careful.
