Many films over the years have used the open matte technique for home video releases and television broadcasts, the most prominent of which include the Back to the Future trilogy, the Jurassic Park trilogy, Schindler's List, Titanic, Top Gun, Willy Wonka & the Chocolate Factory, The Fugitive, and Predator, as well as many films that have been specially formatted for the IMAX expanded aspect ratio of 1.90:1 and 1.43:1. Stanley Kubrick also used this technique for his last three films The Shining (1980), Full Metal Jacket (1987) and Eyes Wide Shut (1999).

Films such as James Cameron's Terminator 2: Judgment Day (1991), Michael Bay's The Rock (1996), and Steven Spielberg's Minority Report (2002), all of which were shot in Super 35 also utilize the open matte technique, but this is mixed with Pan and scan due to the visual effects being rendered in a wider aspect ratio.[1]
Open matte helps in the pan and scan process, as there is more image to work with, and use the extra image on the top and bottom to fill a 16:9 display for HDTV broadcasts. Additionally, filmmakers may choose to release the open matte version for a film's "widescreen" home video release, such as with James Cameron's Avatar and the Blu-ray 3D release of Titanic.
Usually, non-anamorphic 4-perf films are filmed directly on the entire full frame silent aperture gate (1.33:1). When a married print is created, this frame is slightly re-cropped by the frame line and optical soundtrack down to Academy ratio (1.37:1). The movie projector then uses an aperture mask to soft matte the academy frame to the intended aspect ratio (1.85:1 or 1.66:1). When the 4:3 full-screen video master is created, many filmmakers may prefer to use the full Academy frame ("open matte") instead of creating a pan and scan version from within the 1.85 framing. Because the framing is increased vertically in the open matte process, the decision to use it needs to be made prior to shooting, so that the camera operator can frame for 1.85:1 and "protect" for 4:3; otherwise unintended objects such as boom microphones, cables, and light stands may appear in the open matte frame, thus requiring some amount of pan and scan in some or all scenes. Additionally, the un-matted 4:3 version may often throw off an otherwise tightly framed shot and add an inordinate amount of headroom above actors (particularly with 1.85:1), depending upon how well the framing was protected or if the director chooses to create a certain visual aesthetic. With high-definition television now in common usage (with its standardized 16:9 (1.78:1) aspect ratio), the need to reformat 1.85:1 movies for television viewing has virtually evaporated, although television broadcasts still reformat 2.39:1 movies by means of using open matte or pan and scan. For films with wider aspect ratios (2.39:1, for example) the matting bars will appear on the top and bottom of the screen of the broadcast image, thus preserving each director's framing intent.
