Le Grand Bleu
Barr began working in theatre in France in 1986. After finding work in television (including a small role in "Hotel du Lac" (1986), the BBC's version of the Booker prize-winning novel by Anita Brookner), and film, (in particular "Hope and Glory" (1987) by John Boorman), he was cast in the tremendously successful "The Big Blue" (1988). Luc Besson cast him in the role of French diver Jacques Mayol, alongside Rosanna Arquette and Jean Reno. The Big Blue was the most financially successful film in France in the 1980s.
