Sylvester and Czack also share a son named Seargeoh. He was born three years after Sage in 1979, although his exact birth date is unknown. At just 3 years old, Seargeoh joined his father on the cover of People in 1982 around the same time that "Rocky III" was released.
In a June 1985 interview with the magazine, Sylvester revealed his son was diagnosed with autism, which inspired him and Czack to launch a research fund under the National Society for Children and Adults With Autism. Sylvester said he used his film premieres to raise money for the fund.
