The decision was made after the pilot’s table read late last week, which triggered a substantial reworking of the script. While Sagal as the title character was very well received, a number of other elements underwent changes, including the male lead character Alex getting reconceived. That led to the recasting.
Recastings are not uncommon in the pressure cooker of broadcast pilot season when some 70-80 pilots are being made at the same time on tight deadlines. The table read is the first time the key elements of a pilot — script and cast — come together and the producers can see if everything clicks. Nana
