US Oscar-winning actress Halle Berry's sci-fi film, The Mothership, will not be released on Netflix, US media report.

The Hollywood Reporter said Netflix shelved the film because significant reshoots were required at the post-production stage.

Co-producer Berry and her team completed filming in 2021, and the release had been planned for 2022.

Berry and Netflix have not yet publicly commented.

In a preview of new releases back in February 2021, Netflix announced: "Oscar Winner Halle Berry to Star in The Mothership".

It billed the film as as "a sci-fi adventure that follows Sara Morse (Halle Berry) one year since her husband mysteriously vanished from their rural farm.

"When she discovers a strange, extra-terrestrial object underneath their home, Sara and her kids embark on a race to find their husband, father and most importantly - the truth," Netflix's trailer said at the time.

Multiple US entertainment news outlets cited sources saying that lengthy delays to the film's post-production was the streamer's reason for not taking it forward.

The film would have been British Oscar nominee Matthew Charman's directorial feature debut.

Berry has a multi-picture partnership with Netflix: she debuted on the platform as director with her drama Bruised in 2020.

She also co-stars in an upcoming action thriller, The Union, alongside Mark Wahlberg.

Earlier this week, Netflix said its sign-ups boomed at the end of last year as customers prodded by the firm's crackdown on password-sharing created their own accounts.

The streaming company added more than 13.1 million subscriptions in the three months ended in December.

That was the most for any quarter since 2020, extending a streak of growth that started last year.

Netflix said it was confident in its growth path and was planning to raise prices.
