You can rely on Jack Reacher for a lot of things. You got a wrong that needs righting? He's probably your man. He'll put his massive boots on, grab his tiny little phone, and make things happen. That's why Reacher has been such a reliable hit for Prime Video since the very start, because it felt like we were watching the books come to life. Reacher, all stoic and silent, saying nothing but letting his fists do the talking. Absence, however, is not making the heart grow fonder as the series is struggling to keep up momentum ahead of Season 4.

Picture this. A shooter is arrested for opening fire on innocent people and, when questioned, he simply utters the name of the man who he thinks can help him. The man is a wanderer, a vagrant, a hobo. He's a man who has no fixed abode. This all sounds pretty good, right? Well, this would be the perfect vehicle for the biggest movie star on the planet. There's just one problem, and that is that the biggest movie star on the planet isn't 6ft 5in, isn't 250lbs, and isn't blonde.

Over the last few years, Alan Ritchson has quietly become one of the most popular action stars working in Hollywood today. This is largely due to his role in Reacher, the hit Prime Video show with three full seasons already out and a fourth on the way later this year. Prime Video is so sure that Reacher Season 4 is going to be a smash hit — Ritchson has already promised that it’s by far the best season of the show yet — that it’s been picked up for Season 5 before Season 4 even has a premiere date. Ritchson has also expanded into movies recently with hits like The Ministry of Ungentlemanly Warfare, which was directed by Guy Ritchie. Earlier this year, Ritchson headlined the biggest Netflix sci-fi thriller of 2026, War Machine, which has scored over 125 million views.
