"The very best book on Ray Harryhausen's work. John Walsh is a writer to watch."

"Titan of mythology movies left behind a treasure trove of ideas lost and rare material from master animator Ray Harryhausen."
The Guardian
 
"Harryhausen The Lost Movies reveals 80 unmade projects which never saw the light of day and offer a tantalising glimpse of what might have been. With over 50,000 items in the collection, it is the largest of its kind in the world outside the Walt Disney Company. I was amazed by the number of artworks, models, and in some cases, test footage that existed. Cinematic magic."
The Telegraph
 
"A treasure trove of unseen projects, creatures and storylines which sadly never made it to the screen. Harryhausen fans have speculated about these Lost Movies for decades, and now, thanks to John, Titan Books and the Ray and Diana Harryhausen Foundation, we are set to embark on a whole new journey into the imagination of a genius. A wonderful new book."

"Unquestionably, the greatest film visual effects artist gets a fitting book as a tribute to his work."
Book of Man 
 
"If you are passionate about stop-motion animation, the early days of visual effects, Hollywood history or just plain ol' pioneering spirits, this hefty hardcover deserves a place of honour on your coffee table."
Animation Magazine
 
"John Walsh's labour of love book The Lost Movies is a beautiful treasure trove of a book, each turn of the page revealing some beautiful new image or sketch and occasionally even a prototype model of a wonderful new creation that Harryhausen was never able to bring to life. A superb tribute and a fitting testament to a towering and endlessly inventive creative mind, The Lost Movies is beautifully presented with the emphasis very much on the visuals, which, alongside Walsh's considered text, provides the final word on the unfulfilled visions of one of cinema's greatest imaginers."
Starburst Magazine ★ ★ ★ ★ ★
 
"Any fan of Ray Harryhausen and/or monster and fantasy movies is going to love this book. It has been designed to dip in and out comfortably, but you'll probably find yourself reading through it from the beginning to get more of a feel for the timeline and what was possible and when. That is after you've revisited his classics. Celebrate his momentous career with this fantastic, eye-opening book. You won't be sorry."
Review Graveyard
 
"The book is a lovely thing to hold, stylishly designed and full of gorgeous illustrations. The writing is clear, and once Walsh has established himself and his long-standing relationship with the focus of the book and the foundation, engrossing detail is exposed on each of the new discoveries from the archive."
Swigly Animation Magazine
 
"A volume collecting Harryhausen's work on unrealized projects has been long overdue. John Walsh does the master proud. The large landscape format allows never-seen artwork and photos plenty of room to breathe, and anyone who grew up loving stop motion animation will find their imagination soaring with what might have been."
Screen Anarchy
 
"It's a unique way to race an artist's career and gives the reader a new perspective on work that is otherwise familiar."
Imagine Magazine
 
"It's a stunning book."
Infinity Magazine
 
"The production values of this book are absolutely first class; everything from the layouts to the very paper is printing on. There is no doubt that this book is destined to be a classic of its kind and will sell out fast, get a copy, you won't regret it."
