Hollywood actors threaten to boycott Georgia if 'heartbeat' abortion bill becomes law A growing list of Hollywood celebrities signed onto a letter sent to Georgia Gov. Brian Kemp (R) threatening to push film production crews to abandon the state if the pending “heartbeat” abortion bill becomes law.  According to the Atlanta Journal-Constitution, more than 40 prominent actors have already signed onto the letter as of Thursday. Rosie O’Donnell, Gabrielle Union Patton Oswalt, Amy Schumer, Ben Stiller, Sarah Silverman, Don Cheadle, Mia Farrow, Essence Atkins, Uzo Aduba, and Christina Applegate are among those who have signed the letter. The letter, spearheaded by Alyssa Milano, comes a week after the actress tweeted on Friday urging film companies to leave Georgia after the state Senate passed a bill, also known as H.B. 481, that would ban abortions once a fetal heartbeat is detected.
