Will Ferrell played an obsessive collector in The Lego Movie where he had built an incredible set up of buildings, settings, vehicles and characters. While the fictional collection took up a huge space in Ferrell's basement, it's absolute child's play compared to the real-life assembly concocted by Simon Pickard.
The master builder doesn't keep his assortment of Lego gear in a basement, he has five sheds in his garden.
The 38-year-old estimates he has around a million individual pieces in plastic boxes on hand for whenever he wants to build something extravagant.
Stepping on a single brick can hurt like the heat of a thousand suns, so you can imagine Simon would have to have a pretty good system in place to ensure none of them are left lying on the ground, waiting for some poor soul to tread on it.
The dad-of-five says his wife would probably divorce him if she knew just how much he had spent on Lego products over the years.
He's told the Mirror: "It is incredible how much it can cost. I go to the Cardiff Lego store once a month and I don't come away without purchases of up to three figures."
It's not hard to see why. Check out this intricate world he created, which would have required plenty of individual bricks.
While some people won't have picked up a Lego set in years, Simon says it's a hobby which has stayed with him for decades. He said: "Lego's about what you put into it. I played a lot of games with Lego when I was younger. As I've grown older, it has become much more of a creative medium for me."
Building a simple car or house can be hard enough, but Mr Pickard manages to create his elaborate scenes while dealing with a rare condition that causes paralysis in his left wrist.
He's gearing up to show off his latest creation at a four-day event in Birmingham called Bricklive. Simon has been working for the last four weeks to create a replica of the Monaco F1 hairpin. He said he had to develop a new technique to reproduce the curving road, considering Lego blocks are usually rectangular.
The master builder definitely has an arsenal that young kids would probably go wild for. He says that while it's a seriously expensive hobby, he can make money from it through fans wanting to buy or rent his designs.
