Thora’s mother was born in New Jersey, under the surname “Campau”, which is usually French.
Her career's slow decline fell under the radar, but thanks to humor site Cracked pointing it out to us, we can see what probably happened: her dad didn't butt out, even when she filmed sex scenes.
In 1988, Thora made her film debut in Purple People Eater, for which she won a Youth in Film Award.
Later on, Birch starred in the television series Day by Day.
Her other major projects included Train, Winter of Frozen Dreams and Petunia.
Thora resumed her acting career in 2016 after taking a break from acting and performed the character of software engineer Morgan in the television series Colony.
