The filmmaker pleaded guilty to a charge of having unlawful sexual intercourse with a minor in 1978, but fled to France before he could be sentenced.
He was finally captured by authorities in Europe last month and is behind bars in Switzerland while officials decide whether to extradite him back to the U.S.
And Fox admits he wouldn't have been accountable for his actions if it had been a member of his own family involved in the case.
He tells Parade magazine, "If it had been my daughter who was barely a teenager -- my daughter is 15 -- Roman Polanski would be missing... period. It wouldn't even get to the court case. But, that's me and I wouldn't want anyone else to follow that because you should let the justice system work it out. This whole issue is bigger than Roman Polanski."
