Leonardo DiCaprio�s film production company is set to develop a film based on the life of LSD advocate Timothy Leary.

DiCaprio knew Leary prior to his death in 1996 and has been anxious to make a film about him for sometime.

According to the Hollywood Reporter, DiCaprio�s company has now employed the talents of the award winning playwright Craig Lucas to develop a screenplay.

The film will reportedly focus on Leary�s life between his enrolment at West Point military school in the 1940�s to his escape from prison in the 1970�s.
