The official Cannes description of the 2012 restored screening says the version shown there was 4 hours 15 minutes long and featured "25 minutes never screened before." That directly conflicts with the article's claim that the restoration included 40 additional minutes.

There were long-running discussions about missing material from Sergio Leone's preferred cut, which may explain the confusion, but the specific 2012 restoration screened at Cannes was described by the festival itself as adding 25 minutes, not 40.

James Woods did win the Emmy in 1987 for Promise, but the film itself is a 1986 television movie. Reliable film listings identify Promise as a 1986 production and give its TV release date as December 21, 1986.

So the year attached to the movie title here is off by one: 1987 is the awards year, while Promise is correctly dated 1986.

Salvador is consistently cataloged as a 1986 film. The American Film Institute lists it as "Salvador (1986)" and gives its release date as March 5, 1986.

The likely source of confusion is that James Woods' Oscar nomination for the movie was at the 1987 Academy Awards, but the film itself is still a 1986 release.
