Salvador (1986, UK/US)

In director Oliver Stone's political thriller about the bloody 1980 civil war strife in Central America:

• the heavy-drinking, joke-telling drive south in a Mustang convertible into politically-unstable El Salvador by two adventurers: sleazy, obnoxious freelance American photo-journalist Richard Boyle (Oscar-nominated James Woods) and his drug-taking DJ buddy Doctor Rock (James Belushi)
• the horrors of war (stinking piles of corpses of raped/murdered victims) that were uncovered when Boyle and John Cassidy (John Savage) found themselves shooting at the body dump
• the scene in a San Salvador cathedral when Boyle sought redemption and forgiveness from a priest but realized "that's gonna be a little tough" to change his ways
