John Rambo's name comes from a French wine bottle.
David M & his wife were out buying wine and he remarked how; Rambo would be a interesting character name.

PS;
www.imdb.com states that actor Dustin Hoffman declined the First Blood Rambo role. That would of been a interesting film. Screen legend Kirk Douglas was in place to co-star as COL Sam Trautman but left days before the filming.
