Generally, copyright in literary, dramatic, musical or artistic work ends after 70 years, starting from the end of the calendar year in which the author (or if more than one, the last surviving author) dies.
If the author is unknown, copyright ends either 70 years from the end of the calendar year in which the work was made, or if made available to the public in that time, at the end of the period of 70 years from the end of the calendar year in which it was made available to the public.
Making a work available to the public includes:
Copyright lasts for:
Copyright lasts for 70 years from the end of the calendar year in which the death of the last to die of the specified persons occurs.

Where the identity of none of the specified persons is known, copyright last for 70 years from the end of the calendar year in which the film was:
Making available to the public includes showing the film in public or communicating it to the public.
For films where none of the specified persons exists, copyright expires 50 years from the end of the calendar year in which the film was made.
Copyright in broadcasts lasts for 50 years from the end of the calendar year in which the broadcast was made.
Copyright lasts for 25 years from the end of the calendar year in which the edition was first published.
More complex rules apply to films and to literary, dramatic, musical or artistic works, if the 'country of origin' is not the UK and the author is not a UK national. Generally, where a work is unpublished, or was not first published in a country that signed up to the Berne Convention, its country of origin is generally the country where the author is a national. More complex rules also apply to sound recordings or broadcasts if the author is not a UK national.
For these types of work, generally, copyright lasts for as long as it would in either the country of origin (in the case of literary, dramatic, musical or artistic work, or films) or the country where the relevant author is a national (in the case of sound recordings or broadcasts). However, this is dependent on it not being longer than the relevant period of protection provided under UK law.
This is because, in the UK, for non-UK works, copyright lasts for either the duration offered in the UK or the country of origin of the work – whichever is less.
