Today’s edition of 20/20 is scheduled to be a special devoted to “Roseanne – The Return,” examining the impending comeback of one of the network’s all-time biggest sitcom hits, Roseanne. Taking part in interviews are former – and future – series regulars Roseanne Barr, John Goodman, Laurie Metcalf, Lecy Goranson, Michael Fishman and Sarah Chalke, who in the original series portrayed the working-class Conner family (including, in the case of Goranson and Chalke, both Beckys). I wouldn’t be surprised, however, if this scheduled special were delayed so that 20/20 could provide continued coverage of yesterday’s horrific Florida school shooting.
