Cast your mind back to the so-called "flopfest" season that is January. Only five short months ago, Chris Pratt and Rebecca Ferguson were fronting Mercy, a new movie following a man falsely accused of murder, only to be tried by an AI-generated court.

The premise is simple: Make the AI judge believe you're innocent through a numerical threshold, and you walk free. Don't, and you die. There's no lawyer or jury — just your brain and access to your life via curated digital files.

After its theatrical release, it has been on Prime Video for the majority of 2026, and I cannot discourage you enough from watching it. It's far from the worst movie of the year so far, but it's bad enough to be a must-miss.

Without boring you too much, the production feels cheap, it struggles to retain momentum, and Pratt (whose character is hilariously also called Chris) being restrained in a chair for 90% of Mercy's runtime runs thin incredibly quickly.

But let's not talk about Mercy... instead, we need to focus on the movie Pratt recommended as a double bill. Not only does it serve as inspiration for Mercy's action, but it's arguably the most underrated Christopher Nolan movie all time.

Perfect timing ahead of The Odyssey, don't you think?

Chris Pratt reveals Christopher Nolan's Memento is a huge inspiration — and you need to stream it ASAP

"There's a little bit of Memento in this," Pratt told me shortly before Mercy's release.

"This is a character who does not know what's going on, and he's unpeeling the layers of his reality as he learns in real time what has happened."

As soon as he mentions it, I remember just how much of an astonishing viewing experience it was. Starring Guy Pearce and Carrie-Anne Moss, it follows insurance investigator Leonard Shelby (Pearce), who suffers from anterograde amnesia.

He uses notes and tattoos to hunt for the man he thinks killed his wife, which is the last thing he remembers. This means that we know as much as he does, making it one of the most unique and interactive crime thrillers of the last 26 years.

You're thrust back and forth in time with so much confusion that you're wondering if you killed your ex-wife. It's no secret just how much of an exceptional director and storyteller Nolan is... but this was only his second movie.

The talent was already off the scale, but it's no surprise that, given just how many corkers came out more recently (his Batman trilogy, Inception, and Oppenheimer, to name a few), Memento has been put on the collective back burner.

For Matrix fans, Carrie-Anne Moss is also the best female lead that Nolan could have picked. Add in sharp 2000s vibes and lashings of desperation, and you're about to stream a movie you'll never forget (unlike Mercy, which you hopefully do immediately).
