copyright issue for distorting loops

["petr" <petr@tryi.com>]

I want to loop two or three sentences from an older movie (The Bride
of Frankenstein) and put it on a song on my CD.  Can anyone advice to
what degree I need to manipulate, twist, distort or whatever the
sample, so I don't get in trouble with copyright issues?

I know there used to be a lot of talking at LD on the copyright
subjects but I cannot locate what I need in the archives.

thanks
