More from AIP: UP IN THE CELLAR (1970) became THREE IN THE CELLAR to trade off on the popularity of THREE IN THE ATTIC. I saw both on a drive-in double bill.
ANGEL, ANGEL, DOWN WE GO (1969) from American-International became CULT OF THE DAMNED.
A list of retitled films from Sam Sherman's Independent-International Pictures would take a lot of time to compile.
