According to Variety, Steven Spielberg has decided his next project will be an adaptation of the Pulitzer Prize-winning play Harvey, which also was the subject of a 1950 film starring Jimmy Stewart. Harvey focuses on a man and his friendship with a six- foot-tall invisible rabbit. The new film will be based on a screenplay by author Jonathan Tropper (This is Where I Leave You).
