Features many interviews shot for but ultimately unused in Boris Karloff: The Man Behind the Monster: Norman Jewison, Lee Grant, H.M.Wynant, Caroline Munro, Nehemiah Persoff, Diane Aubrey, Donnie Dunagen, Sharyn Moffett, Virginia Bates, to name a few. Boris Karloff:The Rest of the Story features extended material with all of the above, discussing their experiences working with or hearing about Boris Karloff.
Opening Credits describe The Rest of the Story as a "Roughcut Production" a humorous reference to the fact that many of the interviews featured, still have the green screen visible behind the individuals - green screens were only replaced with background images on the final post-production pass for The Man Behind the Monster which The Rest of the Story is a companion piece to.
Included as a Bonus on the BluRay & DvD release of Boris Karloff The Man Behind the Monster (Oct 18th 2022)
