He is best known for his roles in "American Graffiti" (1973), "The Buddy Holly Story" (1978), "Never Cry Wolf" (1983), "Starman" (1984), "The Untouchables" (1987), "Deep Cover" (1992), "Speechless" (1994) and "Deep Impact" (1998).

The Day of the Dolphin is a 1973 American science-fiction thriller film directed by Mike Nichols and starring George C. Scott.  Based on the 1967 novel "Un animal doué de raison" (lit.  "A Sentient Animal"), by French writer Robert Merle, the screenplay was written by Buck Henry. The Dolphin–Palmetto Interchange, also known as 826–836, is a complex four-level stack interchange in Miami-Dade County, Florida.  It primarily serves as a highway interchange between State Road 826 (SR 826, Palmetto Expressway) and SR 836 (Dolphin Expressway), but also has ramps to surface streets such as SR 969 (Milam Dairy Road) and Flagler Street.  The reconstruction project was completed in phases from 2012 to 2015-2016, at a cost of about $560 million, with related construction beginning in 2009, replacing the old two-level diamond interchange.  The interchange was considered well beyond safe capacity, serving over 400,000 vehicles per day.  The reconstruction was the final phase in a 12-step program to improve the highly trafficked Palmetto Expressway, though in 2014 a new project to add express lanes to the Palmetto Expressway was proposed, to begin construction in 2016.  Much work also remains for the Dolphin Expressway.  Work took place with phased detours, closures, and openings.  All roads involved were kept open throughout construction.  Much of the new interchange opened in October 2015, including the two highest flyovers, with completion at that point scheduled for March 2016.  By summer 2016, the interchange was objectively complete.  The official announcement came in early October, very near budget ($563 million) but a couple years over time.  The project included moving a drainage canal and construction of 45 individual bridges, with the interchange serving 430,000 vehicles daily.  The main four levels of the interchange are the Palmetto at ground level under the Dolphin Expressway, the Dolphin-to-Palmetto left-hand flyovers, then the Palmetto-to-Dolphin left-hand flyovers on top.  As of 2016, it's the largest stack interchange in Miami (surpassing the Midtown Interchange). Rory Mallinson (October 27, 1913 – March 26, 1976) was an American actor of film and television.

He began drawing as a child inspired by Escher, Dalí and Moebius.  His drawings usually begin with very rough sketches and are intended to capture a moment of tension or eroticism.  His art pushes his audience into areas where people feel less than comfortable, stating that the "US which is so puritanical, our bodies are usually a great source of anxiety and fear".  As a production designer, he has designed over fifteen independent feature films in the past decade as well as numerous commercials and music videos.  He is best known as the director for the music videos "Blue" and "Looking Glass" by The Birthday Massacre, receiving over 4 million combined views on YouTube, and has directed music videos for the industrial band Android Lust.  He has done production design for many films over the years including "Chasing Sleep" starring Jeff Daniels.  Dan's artwork is strongly themed around surrealism and mostly done in pencil.  As an artist he has exhibited widely.  He has been published in numerous anthology art books including "Bio-Mannerism" which also features work by H.R. Giger and Beksinski, and he has been featured in magazines internationally.  David Bowie commented while looking at Dan's art that he has noticed a strong influence of science fiction on contemporary art.  Giger saw a different aspect, saying simply "Very bony."  He grew to adore the cinema of Fellini and later to marvel at Lynch's "Eraserhead".  Rather than pursue a formal education in the fine arts he chose to study the craft of film making and after college he became a production designer working on feature films in New York City starting with his work as a production designer for Hal Hartley in 1990 with Trust and then, in 1992, with Simple Men.

His first film, entitled DOLPHIN, depicts a school of spotted dolphins residing 40 miles north of Grand Bahama island.  Since 1978 Jones has returned countless times to the Bahamas to visit these dolphins and film them.  Some of the dolphins have become internationally famous.  Chopper, a 27-year-old male, was filmed by Jones for the first time in 1979 and appeared in the 2005 PBS film "The Dolphin Defender".
