LONDONBlighty’s Cascade Media Development is putting development funds into period drama “The Lady Who Went Too Far,” penned by “The King’s Speech” scribe David Seidler. It is the first feature to nab coin from the film and TV financer that launched at the Toronto Film Festival. Cascade would not reveal how much it was investing or the budget of “Lady,” which reunites Seidler with “King’s Speech” producer, Gareth Unwin. Seidler adapted Kirsten Ellis’ biography of Lady Hester Stanhope, who rejected London society in the early 1800s to travel across the Middle East. She played a key role in inhibiting Napoleon’s advances toward India. “Getting our development fund off the ground shortly after launching the company has meant that we have been able to move swiftly in providing crucial funding to support the breadth of filmmakers we are working with, both emerging filmmakers through our Cascade Writers Couch and experienced producers,” said Cascade COO Cora Palfrey. Unwin’s Bedlam Prods. is producing with additional support from the BFI Film Fund, among others. A director and cast is yet to be set.
