Fifty-four years after it was published, with sales of the book at 6.5 million copies and counting, Ayn Rand’s 1,000-page magnum opus “Atlas Shrugged” is finally coming to the screen. The $10 million production, part one of a projected trilogy, featuring a no-name cast (Taylor Schilling? Grant Bowler?) and financed entirely by John Aglialoro, a Philadelphia businessman, will be released on April 15.
