That's not accurate. If the character's first appearance is PD, the character is PD. End of debate. As for "post-1923," it is not "life of the artist + 70 years." That's the UK & Canada (with some exceptions for Canada, particularly with comic books). As for the US, many of those characters films, radio programs, serials, etc... are ALREADY in the public domain (and have been for years).
