Bill Cosby is sharing his thoughts following the death of his on-screen son Malcolm-Jamal Warner at the age of 54.
Cosby told ABC News Monday that Warner was always "a great studier" who he enjoyed working with, saying the two continued to speak regularly long after "The Cosby Show" ended.
He went on to refer to the relationship as one where he acted as his mentor.
Warner played Theo Huxtable on "The Cosby Show" for eight seasons, a role loosely based on Cosby's own son, Ennis, who passed away in 1997.
The actor died Sunday during a family vacation on Costa Rica's Caribbean coast after he was caught in a strong current while swimming.
