David R. Bear has made false copyright claims before. Take Hatari! (1962) for example:

Title: Hatari. By Malabar Productions.
Type of Work: Motion Picture
Registration Number / Date: RE0000459859 / 1989-12-27
Renewal registration for: LP0000022962 / 1961-12-31
Title: Hatari. By Malabar Productions.
Copyright Claimant: David R. Baer (PWH)

Variant title: Hatari.

Malabar Productions.


is a fraudulent renewal while

Hatari. By Paramount Pictures Corporation and Malabar Productions, Inc.
Type of Work: Motion Picture
Registration Number / Date: RE0000479374 / 1990-01-02
Renewal registration for: LP0000022962 / 1961-12-31

Copyright Claimant: Paramount Pictures Corporation (PWH)
Copyright Note: Entered under 17 USC sec. 703 C.O. correspondence.

Variant title: Hatari.

is the real one. Maybe you should do more research first before claiming widely accepted public domain movies aren't.

Note for those easily confused : One-Eyed Jacks (1961) is public domain.

I couldn't find the original registration for the movie, but it was renewed:

Type of Work: Motion Picture
Registration Number / Date: RE0000409372 / 1988-12-29
Renewal registration for: LP0000019590 / 1960-12-31
Title: One-eyed jacks. By Pennebaker, Inc.
Copyright Claimant: David R. Baer (PWH)

Variant title: One-eyed jacks.
