Lionsgate has picked up screen rights to Loving Frank, a historical novel about architect Frank Lloyd Wright by Nancy Horan, according to Variety.

John Burnham Schwartz (Reservation Road) has been set to write the script.

Loving Frank tells the pre-WWI story of the affair between Wright and Chicago society matron Mamah Borthwick Cheney.

" 'Loving Frank' unfolds in a unique historical milieu, yet it speaks to a fundamental aspect of human nature, that you can't help who you fall in love with," said Lionsgate production president Alli Shearmur.

No production date has been set.
