How Slow Horses Season 4 Will Show A Different Side Of Jackson Lamb
Lamb’s eccentric and sometimes off-putting habits have been well-documented throughout the first threeSlow Horsesseasons, leading to plenty of oddball comedy alongside the show’s gripping espionage drama. But the new season will show a different side of the character, giving viewers their first glimpse of Jackson Lamb’s home-life. Oldman himself recently teasedSlow Horsesseason 4’s deeper dive into Lamb (viaIndieWire):
In Season 4, it will be the first time we can see inside Lamb’s flat, Lamb’s house. What was really fun: Will said to me, ‘What do you think? What posters would he have on the wall? Would he have any posters or anything?’ You’ll catch it, only in passing really, but books are everywhere. I said, ‘What about a leg broken on the coffee table, but he’s put the books to level it up?
It’s indeed big news to learn that Lamb has his own flat, as it sometimes seems he actually lives at Slough House. Going deeper into Lamb’s life will likely lead to some uncomfortable and even hilarious moments, giving Oldman a chance to shine.Slow Horses, indeed, has always been great at finding a balance between high-tension scenes and more intimate character moments, and it’s likely that season 4 will again perfectly walk that tightrope.
Slow Horsesseasons 1-3 are available to stream on Apple TV+
It’s yet to be seen howSlow Horsesseason 4 might shake up the show’s tried-and-true formula, beyond going behind-the-scenes ofJackson Lamb’s domestic existence, but creator Will Smith likely has a few tricks up his sleeve. The show is good at keeping viewers on their toes, willing as it is to put major characters in peril, and sometimes even kill them off. The new season doesn’t yet have a premiere date, but it’s likely to arrive in the latter part of 2024.
