Short answers, pulled from the story.
Touchstone Pictures was established on the 15th of February 1984 by then-Disney CEO Ron W. Miller. The label operated as an active film production division of Disney during the mid 1980s through the early 2010s.
The first film released under the new banner was Splash, which grossed 68 million dollars at the domestic box office in 1984. Touchstone Films was a brand chosen from over 1,200 potential names with Silver Wind as the runner-up.
The label's highest-grossing film release was Armageddon, which grossed 553.7 million dollars worldwide. Jerry Bruckheimer produced this film as part of his production deal with Disney from 1993 to 2014.
The label was retired on the 2nd of September 2016 following the release of The Light Between Oceans. Disney was uninterested in revitalizing the Touchstone label for production after the DreamWorks distribution deal ended.
Six Touchstone films have received nominations for the Academy Award for Best Picture, including Dead Poets Society, The Insider, The Help, War Horse, Lincoln, and Bridge of Spies. These films were released under the banner that operated from 1984 until 2016.
