I wish to find a site that sets forth earnings of films on video and
DVD release.  For example, I can find that "Paint Your Wagon" has
finally, with re-releases and film club rentals and other
manifestations of its semi-cult status, repaid its initial investment
in unadjusted (for inflation) dollars, and then some, having boxoffice
earnings of over $31,000,000 and initial expenses (in 1969) of about
$20,000,000, a horrendous sum for the time.  But I can't seem to find
any place that will tell me what it's earned in video/DVD rentals, or
from cable royalties.  I will pay $2.50 for a site or several sites
that would do that.

But no more than $2.50.
