In One Hundred and One Dalmatians, Gibson voiced the puppy named Lucky, alongside Mickey Maga, Barbara Baird, Sandra Abbot, and several other children.

In 1999, she testified before a California legislative panel on the need for statutory protection for child actors' earnings.

She had an agent before she was 3 years old, and soon thereafter she began appearing in films. Her income supported the three of them (her mother and her sister).

On television, Gibson appeared in five Playhouse 90 dramas and many episodes of The Red Skelton Show, as well as some episodes of Whirlybirds, and Leave it to Beaver.

In 1958, Gibson portrayed Cary Grant's daughter - with Paul Petersen and Charles Herbert playing her brothers - in the romantic comedy Houseboat, which also starred Sophia Loren.

After the film was completed, Loren gave Gibson a pendant with a houseboat on one side and "To Mimi from Sophia" on the other. Grant gave each of the children a $50 savings bond.

In 1961, Gibson appeared in The Children's Hour, based on the play by Lillian Hellman. Gibson played a schoolgirl at a small private school run by two friends (portrayed by Audrey Hepburn and Shirley MacLaine) who were falsely accused of being in a lesbian relationship which was somewhat risque for its time. Gibson said Hepburn was very nice to the girls, but that "Shirley MacLaine despised kids" and would not speak to them.

By age 19, Gibson, along with other acting friends, found it difficult to get roles due to overexposure, and the casting directors were looking for "new faces".
