Invitation to a Gunfighter is a 1964 DeLuxe Color western directed by Richard Wilson, starring Yul Brynner and George Segal. It was based on a 1957 teleplay by Larry Klein that appeared on Playhouse 90. A lone Creole gunfighter, Jules, burdened by his own past of dealing with racism and prejudices, ends up in a town dealing with its own racist and hypocritical ignominies. Jules attempts to learn the truth about the town's real motives for hiring him, while at the same time reconciling with his own past as he attempts to force the town's white folks to accept their own hypocritical shortcomings in living with their Mexican cohabitants.
