Rospo Pallenberg was born Robert Pallenberg in 1939 in England. He is the son of Corrado Pallenberg, an Italian physician
and author. Before becoming a feature screenwriter, he worked as an architect. Pallenberg met writer and director John Boorman
in New York and the two would go on to collaborate on and off for years, beginning in 1970 when Boorman hired Pallenberg to
work on a film adaptation of The Lord of the Rings novels for United Artists. Pallenberg went on to work on Deliverance and
Exorcist II: The Heretic and was a co-writer (with Boorman) on Excalibur (1981) and wrote The Emerald Forest (1985), all directed
by Boorman. Pallenberg is also credited with Druids and The Barber of Siberia. In addition to credited projects, Pallenberg
worked steadily from the 1970s through the 2010s on unrealized projects, with novelists and independent producers including
John Boorman and Stephen King. In 1989, Pallenberg directed the film Cutting Class, written by Steve Slavkin.
Pallenberg is married to Barbara Pallenberg and lives in Los Angeles.
