Joan Crawford (Jessica Lange)

Crawford become a household name in the 1930s, but her three Oscar nominations (with one win) came in the ’40s and ’50s.

Her feud with Davis came to a head during the 1962 movie What Ever Happened to Baby Jane?, which is the subject of the FX drama, but it actually began decades earlier through competition for parts, awards, and even a man — actor Franchot Tone.

Crawford passed away in 1977 at the age of approximately 73 (her exact birth date is disputed), to which Davis reportedly said, “You should never say bad things about the dead, only good . . . Joan Crawford is dead. Good.”
