True Lies was shot by cinematographer Russell Carpenter (Titanic, Avatar: The Way of Water) on 35 mm photochemical film (in Super-35 “common top” format, with Eastman EXR 50D 5245, EXR 200T 5293, EXR 500T 5296 stocks) using Arriflex 35 BL4, 35 IIC, and 35-III as well as Moviecam Compact cameras, along with Zeiss Standard Speed, Super Speed, and Cooke Varotal lenses. Visual effects were also filmed in VistaVision format. The film was then finished photochemically in the 2.39:1 aspect ratio for theaters (which included 35 mm anamorphic blow-up release prints, as well as 70 mm blow-ups).

For its release on Ultra HD, Lightstorm, working with Park Road Post, has built a new 4K Digital Intermediate using recent 4K scans of the original camera negative (confirmed per Lightstorm). This footage has been “optimized” by Park Road’s proprietary deep-learning algorithms. Photochemical grain has been greatly reduced, though not eliminated entirely, while fine detail has been “enhanced” algorithmically. There are also occasional shots throughout the film that appear to have had a bit of old-school noise reduction applied, but it’s hard to be sure if it’s actual DNR or simply just that the Park Road process has been a little too heavy-handed in places.
