 Dialogue in the final scene reveals that Marnies mother had given up her  virginity at 15 to Marnies father in exchange for a sweater. Just before the  films release the studio had second thoughts about this part, and  Alfred Hitchcock (I) (qv) agreed to cut the lines. But hundreds of prints  had already been made, and rather than incur the cost of reprinting the final  reel of each, the studio released them as they were, so there were two  versions of the film from the outset.
