Winona Ryder and Leonardo DiCaprio are battling it out with Darren Aronofsky to make the first biopic of counter-culture icon Timothy Leary. Ryder, Leary's god-daughter, and her father Michael Horowitz, Leary's best friend, have signed to be creative consultants for a forthcoming project by DiCaprio's production company Appian Way.

DiCaprio's father, comic book writer George DiCaprio, was also a friend of the Harvard University professor and LSD pioneer. Aronofsky is also planning a biopic of Leary, who died in 1996 aged 75, writes the New York Daily News.
