BBC Antiques Roadshow audience gasps after learning massive worth of Blade Runner memorabilia

Antiques Roadshow fans were left stunned as they witnessed a staggering valuation for an extensive trove of Blade Runner paraphernalia during the show.

At Clissold Park, BBC's expert Jon Baddeley engaged with a collector boasting an impressive spread from Ridley Scott's iconic 1982 sci-fi thriller Blade Runner featuring Harrison Ford.

The owner recounted the origin of his collection, saying: "This collection belonged to my dad, he saw the film when it came out in the cinema and again, he wasn't too sure of it himself but he waited until it came out on VHS and he saw it and thought 'Yes, this is great' and started collecting pieces of memorabilia, posters and everything that was coming out at the time."

He expanded on his father's burgeoning obsession by revealing: "And then as his passion grew for it, he decided to go a bit more hardcore and acquire actual pieces from the film himself.

"He started collecting pieces in the late 1990s through to the noughties when things were quite a reasonable price and obtainable at the time. He managed to obtain the stuff directly from crew members themselves," reports the Express.

Baddeley stressed the importance of history behind these items, saying: "With all memorabilia, the provenance is really important."

Detailing the uniqueness, Baddeley acknowledged: "Also there are some quite academic items here like the costume designs, an incredible album, photographs, notes, all the costumes used throughout the film, and that in itself is an amazing museum artifact.

"And behind that, you've got the storyboards which, again, gives you the sequence, the pre-production. They produce all these storyboards and you told me something about the red dots above them."

The owner explained: "Yeah so the red dots here are the approvals from Ridley Scott himself. So the effects team, which was led by Doug Trumbull, would have them all up on the wall.

"Ridley Scott would then come in, have a look at them all, and decide which ones he liked and he'd put little red stickers on there and that would be his approval of 'yep, we're going with that one'."

"Now there's only one of that one. They're not mass produced so those two albums, totally unique," Baddeley highlighted.

Additionally, the collection boasted items like the neon umbrella, Harrison Ford's director's chair, his iconic gun used in the film, and the tattered Zora costume worn by Joanna Cassidy when she was "smashing through glass".

Baddeley called attention to an audacious red crew member jacket, with the guest revealing: "So it was Harrison Ford that apparently got black crew jackets for everyone and he presented a black crew jacket to Vangelis, the composer.

"Vangelis looked at it and was like 'No. No, I want something a bit more flamboyant and that's his own crew jacket."

The expert began the appraisal, stating: "I should emphasise that this is just a small part of your collection, maybe 20-25 percent but I've been totting it all up and I've seen the other items you've brought along today.

"This is a colossally important collection, from an immensely significant film, and if it went on exhibition, crowds would definitely be queuing up for a peek. We're talking cult classic status here. What's it worth? I'd say youre looking at a cool £200,000 to £300,000."

At this revelation, the audience audibly gasped as the guest reacted with multiple wows, saying: "Wow. Wow. Wow. OK. Fantastic. Wow. I mean, for me, for my family, for us, we would like to see it all in a museum, that's what we would like."

He went on to express how he wanted people to enjoy the collection: "The thought of people coming to see it and enjoying it, that's exactly what we want."

Baddeley lauded the owner's father's vision and passion: "And it's an accolade to your dad. He had the foresight. He had the vision. He had the passion. We all want to share in that."

Cherishing the opportunity to share his heritage, the guest added: "It's been great sharing this with everyone and my dad would have been really, really proud.

"He reflected on his fathers humbleness about the treasures: "He loved this stuff but unfortunately it's just been kept in boxes because he didn't think anyone would be interested in it."
