Since Godard is still making films, there's no question it would be him (how can u argue against that?) I wish Bergman was still directing and not just writing obscure plays and scripts. The best living American directors I think are Scorsese, Altman, Allen, Spielberg (leave me alone) and Coppola. The best living foreign ones; Jacques Rivettte, Eric Rohmer, Claude Chabrol, Aki Kaurisami, Almodovar, Angelopolous, Olivieria, and Wong Kar-Wei.
