Slipstream is a film about bicycle racers directed and written by Steven Spielberg and Roger Ernest that went unfinished.
 Ernest later appeared in Spielberg's "The Sugarland Express" and "Close Encounters of the Third Kind".
 "Slipstream" also co-starred Tony Bill, who was already an established actor, and Jim Baxes, who went on to co-star in 1975 in the TV show "SWAT" under the stage name James Coleman.
Encounters Of Every Kind is an album by Meco, released in 1978.
 It was recorded after the success of Meco's platinum-selling album "Star Wars and Other Galactic Funk" and contains two sides of linked songs.
 In contrast to the previous album (which dedicated a full side to the music from "Star Wars") and contrary to an album title that suggests a similar focus on the music from "Close Encounters of the Third Kind", this album is actually made up of songs from a number of different popular movies, with no special focus on any particular film.
 (Meco would return to this format for his 1982 album "Pop Goes the Movies".)
 The music from "Close Encounters" only appears at the very end of the album.
Cinematographer Vilmos Zsigmond, also formerly credited as William Zsigmond, was nominated for four Academy Awards for Best Cinematography ("Close Encounters of the Third Kind", "The Deer Hunter", "The River", and "The Black Dahlia"), winning once for his work on "Close Encounters of the Third Kind".
 He also won two American Society of Cinematographers Awards, one Primetime Emmy Award, and one British Academy Film Award.
Encounters of the Spooky Kind () is a 1980 Hong Kong martial arts comedy horror film written and directed by Sammo Hung, who also starred in the lead role.
 The film was produced by Hung's production company Bo Ho Film Company.
 It was released as "Spooky Encounters" in the US.
 It is sometimes listed as "Close Encounters of the Spooky Kind", more blatantly mimicking the title of the film "Close Encounters of the Third Kind" (1977).
 The film was the progenitor of the jiangshi film genre and one of Hong Kong's first kung fu horror comedies.
Eugene Dynarski (born September 13, 1932) is an American actor.
 Three of the most popular projects that he has been involved with were two Steven Spielberg films, "Duel" and "Close Encounters of the Third Kind", and the Westwood Studios computer game "".
Toyetic is a term referring to the suitability of a media property, such as a cartoon or movie, for merchandising tie-in lines of licensed toys, games and novelties.
 The term is attributed to Bernard Loomis, a toy development executive for Kenner Toys, in discussing the opportunities for marketing the film "Close Encounters of the Third Kind", telling its producer Steven Spielberg that the movie wasn't "toyetic" enough, leading Loomis towards acquiring the lucrative license for the upcoming "Star Wars" properties.
The 28th annual Berlin International Film Festival was held from 22 February to 5 March 1978.
 The festival opened with "Opening Night" by John Cassavetes and closed with Steven Spielberg's out of competition film "Close Encounters of the Third Kind".
 This was the first year the festival was held in February.
Night Skies was a science fiction horror film that was in development in the late 1970s, but was never actually made.
 Steven Spielberg conceived the idea after "Close Encounters of the Third Kind".
 Instead, material developed at the time was used in "Poltergeist" and "E.T. the Extra-Terrestrial".

Melinda Ruth Dillon (born October 13, 1939) is an American actress.
