Is Reefer Madness (1936) public domain?

The evidence we relied on to restore, describe and publish it — in full, so you can check it.

Rights basis on record

The finding, and the working behind it

Public domain in the United States: no registration under any of its three titles in the 1912-1939 cumulative catalog, and no renewal in any volume from 1957 to 1978. The film was made in 1936 as Tell Your Children, recut and reissued for the exploitation circuit, and is best known today as Reefer Madness; all three titles were searched, and so were the producers Dwain Esper and George Hirliman. The registration itself is missing: there is no entry for the film in the Catalog of Copyright Entries cumulative Motion Pictures 1912-1939, the volume a 1936 feature would appear in. Esper does appear in the record, which is what makes the absence meaningful rather than a gap in our reading: his 1975 renewal R606245 is for a different, later film. He knew how to file one, and none was filed for this. The reason usually given for this film being free is that the print carried a defective copyright notice. We did not verify the notice ourselves, and this finding does not rest on it; it rests on there being neither a registration nor a renewal to find. Pre-1951, so the printed renewal volumes 1957-1978 were read, not the online database, which begins in 1978. Copy: the Archive's reefer_madness1938 MPEG-2, 720x480.

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.

The copy, and what we changed

The print we started from: The source print for Reefer Madness on archive.org
Researched: 2026-10-01
What we did to the print: 246 described cues across a 68 minute 22 second runtime, filling 18 minutes 10 seconds of gaps between dialogue -- 26.6 percent of the film -- at 166 words per minute.; Figures measured from the shipped sidecar and the shipped master.; The original soundtrack was repaired from the Archive copy: rumble filtered below 60 Hz, the top end rolled off above 5 kHz, loudness matched in two passes.; Described track flagged default and visual_impaired, with the original audio kept as a separate selectable stream.; Captioned verbatim: 640 cues, every disputed line ruled by Mike.

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 [email protected] 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.
