Is The Amazing Mr. X (1948) public domain?
The evidence we relied on to restore, describe and publish it — in full, so you can check it.
Public domain in the United States
The finding, and the working behind it
US public domain: registered as THE SPIRITUALIST, LP1730, Pathe Industries, 7 Jul 1948 (printed Catalog of Copyright Entries, 1948 Motion Pictures). No renewal in the printed CCE renewal sections for 1975, 1976 or 1977 under either title or the number, while National Telefilm Associates, successor to the Eagle-Lion library, renewed seventeen adjacent Eagle-Lion titles of 1947-48 in those same volumes (T-Men, Railroaded, Adventures of Casanova, Check Your Guns and the rest) and skipped this one. Term expired 31 Dec 1976. Source copy is an archive.org upload that is a standard-definition telecine upscaled to 1080x720, not the separately copyrighted 2019 Blu-ray restoration (different framing, no ident). Verified 1 Sep 2026; evidence excerpts kept with the master.
How to check this yourself
Everything above is drawn from public records. None of it requires our word:
- The Catalog of Copyright Entries, the Copyright Office’s printed registration and renewal volumes, scanned and searchable at the Internet Archive and at the Online Books Page. Registration numbers beginning LP or MP are film entries.
- The Copyright Office online records at copyright.gov, which are complete from 1978 and therefore decisive for any renewal that fell due from then on.
- The NFPF Field Guide to Sponsored Films, for the industrial and educational titles, which records copyright status entry by entry.

What this does and does not mean
This is a finding about United States copyright, made in good faith from the public record. Copyright terms differ by country, and a film in the public domain here may still be protected elsewhere.
A negative search proves that no record was found, which is not identical to proving that no record exists. The Copyright Office says as much about its own catalogs. Where a search could not be decisive we say so above rather than rounding it up to certainty.
Restoring a public domain film gives nobody any new rights over the film, including us: this print is free to take, use and pass on, exactly as the original is.
The audio description is not part of that. It is an original work written and recorded by Always on Top Entertainment LLC — free to listen to here, and licensed separately for reuse. If you hold a right in this film and we have it wrong, write to mike@tapeterritory.com and we will take it down while we check.

Why we did this research
Establishing what may be published is the first step before restoring a film and writing an audio description for it. That is what this site is for, and we do the same work on commission — audio description and captioning, with published rates.
