Who didn't show up for the first "Roseanne" reunion episode?

The Roseanne revival has begun production, and the cast is back in action — with one notable exception. The sitcom’s stars reunited on set Tuesday for a table read of the revival’s premiere episode, entitled Twenty Years to Life. ABC released several photos of the cast and crew laughing as they go over the script for the episode that airs in 2018.

… Among the cast members on hand were Roseanne Barr (Roseanne), John Goodman (Dan), Sara Gilbert (Darlene), Laurie Metcalf (Jackie), Michael Fishman (D.J.), Lecy Goranson (Becky) and Sarah Chalke, who also played Becky but will originate a new character.

… Not in attendance was Johnny Galecki (David), and ABC says that there is no confirmation on whether the Big Bang Theory star will participate in the reboot. The network said in August that talks with Galecki “are still in progress.”
