With a “Roseanne” reboot coming to television on March 27, there are a few interesting facts about the show that you should know about before watching again after 20 years. Many of the writers for the show wrote scripts for other big hits that include “Buffy the Vampire Slayer” and “The Big Bang Theory.” In order to work in the death of Glenn Quinn in real life, “Roseanne” will offer details about Mark either leaving Becky or dying on the show. While the series aired in the 1990s, Roseanne was married to three different people, all who made guest appearances on the show. If you’ve seen the pilot episode of the show, then you know that there was another boy who played D.J before Michael Fishman took over.
