Eddie Constantine (born Edward Constantinowsky 29 October 1917, Los Angeles, California – 25 February 1993, Wiesbaden, Germany) was an American-born French actor and singer who spent his career working in Europe.
He became well known for a series of French B movies in which he played secret agent Lemmy Caution and is now best remembered for playing the character in Jean-Luc Godard’s philosophical science fiction film Alphaville.
A cult figure, Constantine also appeared in films by Rainer Werner Fassbinder (as himself in Beware of a Holy Whore 1971), Lars von Trier, and Mika Kaurismäki. He continued reprising the role of Lemmy Caution well into his 70s; his final appearance as the character was in Jean-Luc Godard’s Allemagne année 90 neuf zéro (1991). —Wikipedia
