This immense low-budget sci-fi starring Sam Rockwell has everything. It has Sam Rockwell. A Clint Mansell score. A claustrophobic retro set and gorgeously moody moonscapes. Hard sci-fi ideas. The basic premise: A man coming to the end of a three-year solitary stint on the far side of the moon suffers a personal crisis. A must-watch.

A routine blockbuster for reliable entertainment.

A warning for the body horror-averse before hitting play on this David Cronenberg sci-fi. Scanners follows people with special abilities, including telepathic and telekinetic powers.

Robert Rodriguez isn't the most popular among Star Wars fans at the moment, mainly for making a character do a pointless ballerina twirl in the divisive The Book of Boba Fett finale.

Timothée Chalamet, Rebecca Ferguson, Oscar Isaac, Zendaya and more stack out a hugely impressive ensemble cast.

With the latest season of HBO's Westworld currently airing on TV, you may as well go back and watch its source material, if you haven't already. The premise is pretty much the same as the series: An adult amusement park transports visitors to themed worlds, including a Western World.

This solid British sci-fi comes from Gareth Edwards, who went on to direct Rogue One: A Star Wars Story and 2014's Godzilla.

If you haven't seen The Matrix, and somehow don't know its major plot points, well done for avoiding spoilers for 23 years. The sequels Reloaded, Revolutions and Resurrections are also on HBO Max.
