Kevin Costner talks with Jimmy Carter about Wyatt Earp 1994

Costner was originally involved with the film Tombstone, another film about Wyatt Earp, written by Kevin Jarre of Glory. However, Costner disagreed with Jarre over the focus of the film (he believed that the emphasis should have been on Wyatt Earp rather than the many characters in Jarre's script) and left the project, eventually teaming up with Kasdan to produce his own Wyatt Earp project. The film was also originally meant to be a six-hour miniseries until Kevin Costner joined the cast. Costner proceeded to use his then-considerable clout to convince most of the major studios to refuse to distribute the competing film, which affected casting on the rival project
