Unfortunately I've seen this happening with many industries across the world,once the actress is married & have pregnancy changes in the body,casting directors starts looking for new unmarried actresses no matter how big of a star that actress was before.
actress go ah-sung revealed that married actresses face restrictions right from the casting stage.
on the youtube variety show โ๋์์ฌ์๋ํผ์โ ep 3, which was released on the 14th, go ah-sung responded to the question, โdonโt actresses worry about โlimitations in rolesโ once they get married and have children?โ by saying, โsince iโm still unmarried, I havenโt experienced it firsthand, but when i hear stories directly from people in the industry, actresses got cut (at the casting stage) simply because โisnโt this person married?โ itโs really bad for actresses.โ
unless the actresses are top stars, it must be really tough for them..
