Imagination is everything. It is the preview of life's coming attractions

We searched Einstein's collected works and the standard scholarly reference on his sayings, and found no primary source—no letter, essay, book, speech, or interview transcript—containing the sentence "Imagination is everything. It is the preview of life's coming attractions." What Einstein genuinely said about imagination is well documented, most famously "Imagination is more important than knowledge" from his 1929 interview with George Sylvester Viereck, and that authentic line is routinely blended with the "coming attractions" phrasing to produce this composite. The strongest documentary trail we found points elsewhere: the key sentence appeared in a 1940 Los Angeles Times advertisement for a real-estate development called Friendly Hills—"Imagination is the preview of life's coming attractions"—with no mention of Einstein, which predates its attachment to his name and reflects an American cinema-marketing idiom ("coming attractions") foreign to his era and style. The book matches we located (such as *Motivating Thoughts of Einstein* and *Imagination, Creativity, and Responsible Management in the Fourth Industrial Revolution*) all simply repeat the attribution without any citation to an original Einstein document, and thus carry no evidentiary weight. Because we have a specific, citable earlier appearance of the line in anonymous 1940 advertising copy—not merely a failure to find an Einstein source—the balance of evidence points positively away from Einstein. We assess this quote as misattributed.
