“For an indie sci-fi, it looks deceptively expensive. The cast does the best they can with limited roles that were probably significantly more paper-thin on the written page […] In spite of one strong segment that feels cute and funny, Warning has nothing to say that will be of much interest.” Josh at the Movies

“There’s a bit of action, a bit of narrative humour and all in all it’s an entertaining and enjoyable film. The effects are also pretty spectacular for a film with such a low budget. It’s an interesting, almost moreish film, yet only mildly thought-provoking when it could have been thought engaging.” Lost Woods

Warning is a very lucid and well-honed comedy-drama […] The film criticises or has concerns about our future and technology. More specifically, it works as an essay on the control of our life or even our mind and body or that of others. It is suggestive enough to be considered interesting. It’s quite sarcastic about life.” Moviementarios [translated from Spanish]


In the US, Warning will be released by Lionsgate theatrically in select locations, On-Digital and On-Demand on October 22, 2021.

In the UK, Warning will be released by Signature Entertainment on On-Digital Platforms and DVD on 25th October 2021.
