Deadline reports that a new lawsuit from the author states the film is too similar to his 1965 novel Repent, Harlequin! Said the Ticktockman. He now wants to block the release and receive compensatory damages.
The science fiction author is well known for his work and also his lawsuits. After he sued over The Terminator, he received an acknowledgment credit. He has also sued CBS-Paramount over a Star Trek episode for which he claims they failed to pay him for. That one happened 42 years after the episode aired.
According to the lawsuit, Ellison recently had a third party working on an adaptation of the short story after refusing adaptation offers for many years. The suit claims the unauthorized adaptation will hurt and possible sale and their reputation.
The suit alleges that plot and character parts were lifted. While their is quite a bit of evidence in their favor, it’s unlikely that it will shut the movie down. For their defense they also note that Richard Roeper said In Time was based on the short story.
