Barr wrote in a subsequent tweet how special the reboot is to her: "This 10th season of 'Roseanne' is just a dream come true for an old lady comic who fought so hard 2 honor working class ppl in America."
Executive producer Whitney Cummings also tagged Galecki in an Instragram photo on the "Roseanne" set, indicating that the "Big Bang Theory" actor is definitely coming back to play David.
According to Hollywood Life, David and Darlene (Sara Gilbert)'s children have been cast for the revival: Emma Kenney (Deb on "Shameless"), will play their now 14-year-old daughter, Harris. Newcomer Ames McNamara will play their 8-year-old son, Mark, who was named after David's brother, played by Glenn Quinn. Sadly, Glenn, who also starred on "Angel," died in 2002 of an alleged drug overdose.
The "Roseanne" revival will air on ABC in 2018.
