The publishers of Woody Allen's autobiography, Apropos Of Nothing, have reportedly threatened to sue HBO and the makers of the docuseries, Allen V Farrow, if they fail to furnish evidence for authorised use of audio from Allen in the documentary.

Allen V Farrow investigates the sexual abuse allegations levied against Woody Allen by his adoptive daughter Dylan Farrow. The use of the audio clip in the docuseries has been a talking point ever since the first episode aired recently.

Skyhorse Publishing has sent a 'litigation hold document' to HBO and filmmakers Amy Ziering and Kirby Dick, claiming that the makers of the docuseries haven't procured the proper clearance to use portions from Allen's audiobook.

"The document preservation notice could reveal if Ronan Farrow exerted any influence on HBO to green-light the series — or whether he had involvement with the filmmakers in presenting a very subjective view of the long-running feud between Woody and his ex-wife Mia," said a source to Radar Online. 

The network had signed a deal with the divorced couple's son, Ronan Farrow, for the documentary last year.
