Released on 28 March 2025, Time Travel Is Dangerous is a wildly entertaining sci-fi comedy with sharp humour, clever twists, and a fantastic cast. Directed by Chris Reading, the film is based on his original short, which was created for the SCI-FI-LONDON 48-Hour Film Challenge, our film competition that is known for producing innovative and imaginative short films in a weekend!

Time Travel Is Dangerous stands out because of its ability to balance comedy with high-concept sci-fi. The film embraces the chaotic consequences of time travel, leaning into its absurdity rather than trying to over-explain the mechanics.

The cast is superb, bringing the right mix of energy and comedic timing. Whether it’s hapless time travellers getting themselves into increasingly ridiculous situations or a villain with a delightfully convoluted master plan, every performance adds to the film’s charm.

For those who love time-travel comedies like Back to the Future, Bill & Ted, or Galaxy Quest, it’s a great example of how a simple, well-executed idea from a short film can be expanded into something truly special.

Whether you’re a sci-fi 48hour alumni or just looking for a fun, fast-paced adventure, Time Travel Is Dangerous is a hilarious, high-energy ride that proves once again why SCI-FI-LONDON is a breeding ground for great indie sci-fi, if we don’t say so ourselves.

Time Travel Is Dangerous is coming to UK cinemas from 28th March

The next 48hour challenge is 26 – 28 April 2025
