Although there is definite confirmation about the series' revival, the network has decided not share any details. ABC and the producers have agreed upon 9 episodes so far with the first one titled 'Twenty to Life'.
The first table-reading has been done in October, and it was so heartwarming to see the cast back together. Even John Goodman was called for the project even though he 'died' in Season 9. It will be fun to see how will the writers deal with his on-screen death.
Johnny Galecki will reprise his role in 2018
It wasn't Johnny's first role back in 1992, but it was the turning point in his life. The role of David Healy secured him a place among the acting community, and Galecki is more than grateful for it. That is why in spite of his obligations towards 'The Big Bang Theory', Galecki will be joining the revival cast albeit for just one episode.
