The Dean Martin & Jerry Lewis Collection Volumes 1 and 2 were re-released by Warner Archive. I thought that Paramount owned the DVD rights to the Dean Martin and Jerry Lewis movies.
Paramount does, and for three decades has expressed little-to-no interest in marketing its film library (unless it's STAR TREK, INDIANA JONES, THE GODFATHER, etc.). The studio's outsourced its classic films to Olive Films for several years, and began doing so with Warner Archive last year.
