Ridley Scott is shooting his first film in 3-D, and he says he'll always use the multidimensional approach in his future films.
The director appeared at Comic-Con via satellite from Iceland, where he is shooting the sci-fi thriller "Prometheus."
Scott said 3-D doesn't just enhance action sequences, it "opens up the universe of even a small dialogue thing."
The filmmaker said, "I'll never work without 3-D again."
"Prometheus" star Charlize Theron appeared on stage at Comic-Con and co-star Noomi Rapace appeared alongside Scott in Iceland.
The film explores questions of alien DNA and is set for release next year.
Comic-Con continues through Sunday at the San Diego Convention Center.
