A sound blimp was built to quiet IMAX cameras during dialogue scenes in The Odyssey (2026).
IMAX film cameras are large and mechanically noisy, which can make it difficult to record clean dialogue. For close-up scenes requiring audible performances, the cameras were concealed inside large sound blimps designed to mute their operating noise.
The production also used a system of mirrors so actors could maintain eye contact when the camera blocked their direct view. These solutions addressed practical problems created by the film’s decision to use IMAX cameras throughout the feature.
The sound blimp should not be confused with a waterproof housing or a visual-effects device. Its purpose was acoustic: reducing camera noise so dialogue could be recorded on set while preserving the large-format image.
