Not so supercalifragilistic …

Disney is developing a completely unnecessary new "Mary Poppins," to be directed by Rob Marshall ("Chicago") with songs by Marc Shaiman and Scott Wittman (TV's "Smash"). The studio says it will be based on P.L. Travers' later Poppins novels, but don't call it a sequel!

Tall tale collapses

Comedian Steven Rannazzisi (FX's "The League") has admitted in a series of contrite tweets that his often repeated story of a harrowing escape from the World Trade Center on Sept. 11 was fabricated. "I was in Manhattan but working in a building in midtown and I was not at the Trade Center on that day," he said. "This was inexcusable. I am truly, truly sorry.
