Castle Rock hobbyist’s hand-built Millennium Falcon sells for $350,000

Castle Rock resident Sean Sides turned a decades-long Star Wars obsession into a $350,000 sale when his hand-built Millennium Falcon replica crossed the auction block on May 4. The five-foot filming miniature replica drew the winning bid at Heritage Auctions’ Star Wars Day sale, putting a Douglas County hobbyist at the center of a collector market that rewarded extreme patience, technical skill and pop-culture authenticity.

Sides built the ship around a steel pipe frame and filled it with vintage kit parts in the same style used by the original filmmakers nearly 50 years ago. CBS Colorado reported that the model contained about 3,000 individual parts drawn from more than 170 model kits, spanning planes, ships, boats and armor. Heritage described it as meticulously hand-built using original Industrial Light & Magic techniques and more than 3,000 vintage model kit components.

There was no blueprint to follow, so Sides relied on forums, color-coded part databases and his own technical drawings to recreate the Falcon’s proportions. He hunted hard-to-find vintage kits on eBay and other channels, then assembled the replica piece by piece in a basement workshop and museum he created with his wife’s support. The project took nearly four years to complete, and its scale reflected the kind of long-term, specialized labor that can turn a private obsession into a high-value asset.

His connection to the ship goes back to 1977, when he was 10 years old and saw Star Wars 13 times that summer. He later said Battlestar Galactica helped spark his fascination with spacecraft, but George Lucas’ original film turned that interest into a lifelong modeling pursuit. That history helped give the Falcon more than sentimental value: the replica was selected for display at the Academy Museum of Motion Pictures and used in demonstrations of John Dykstra’s Dykstraflex motion-control camera system, a sign that its craftsmanship was taken seriously by people tied to the original films.

Heritage said the May 4 Star Wars Day auctions drew more than 1,600 bidders and brought in more than $3.6 million combined, underscoring the strength of the market that drove Sides’ model to six figures. For Castle Rock, the sale was a reminder that specialized skill, online collaboration and years of patient work can create real economic value far beyond the basement where the project began.
