There's a tiny reference to a screen adaptation of David Foster Wallace's Little Expressionless Animals (one of the short stories in Girl With Curious Hair, which first appeared in The Paris Review - read it here ) at the end of this piece from Cinemablend.com:
Park Pictures also confirmed that Frank is the first of several planned features on the narrative feature company's to-do list, which also includes a new project from British director Ringan Ledwidge, an adaptation of Sam Lipsyte's best-selling novel The Ask, and an adaptation of David Foster Wallace's short story, Little Expressionless Animals.
