When the Blaxploitation era ended, many of the careers of those stars ended as well, but Thalmus Rasulala managed to keep steady work within the Hollywood system. I believe part of this was because of his excellent portrayal of Kunta Kinte's father in the popular mini-series Roots.
Although the movie parts and television guest staring roles that followed weren't always as large or memorable as the characters he portrayed in the 1970's, Thalmus Rasulala was a working actor with a powerful screen presence that one couldn't help but notice.
Sadly, he is no longer with us. On October 9, 1991, Thalmus Rasulala suffered a heart attack shortly after filming his last scenes in Mom and Dad Save the World and passed away at the young age of 51.
