Spot Marks the X is a 1986 American crime comedy television film that starred Mike the Dog (from Down and Out in Beverly Hills) as Capone/Astro, Barret Oliver (from The Neverending Story, Frankenweenie, D.A.R.Y.L, and Cocoon) as Ken, and Natalie Gregory (from Alice in Wonderland (1985 version), Oliver & Company, and Cranium Command) as Kathy, who, unlike her role as Alice in the aforementioned 1985 version, is seen with her real hair in this movie, which is brunette. It was produced by Gregory Harrison's production company, The Catalina Production Group, Ltd. in association with Walt Disney Television.

The film originally aired on October 18, 1986, on The Disney Channel, then a premium cable TV channel. Because of this, it originally aired without commercials. It would later air on May 17, 1987, on ABC in a 2-hour format as part of the Disney Sunday Movie. It also aired in a 2-part format on that show, with part 1 airing on July 3, 1988, and part 2 airing the following Sunday. Filmed on location in Vancouver, British Columbia, Canada from early-mid 1986. According to the book How I Broke Into Hollywood: Success Stories from the Trenches, director Mark Rosman was about to begin work on this movie in early 1985, shortly after finishing up The Blue Yonder. But then the 2-week writers' strike, which demanded more money for home video sales, occurred. This movie was one of three different Disney Channel Original Movies directed by Mark Rosman, the other two were The Blue Yonder (1985) and Life-Size (2000). In addition, Rosman has also directed episodes of two Disney Channel Original Series' in Even Stevens and Lizzie McGuire. He also directed Hilary Duff in A Cinderella Story and The Perfect Man.
