According to a Variety story on an unrelated movie, one of the films listed as those that Samuel L. Jackson has recently completed working on includes Iron Man. It's a minor detail tucked away at the very end of the article.
Jackson has been rumored to be playing Nick Fury, a hard-boiled ex-military man who runs S.H.I.E.L.D., a worldwide counter-terrorism and intelligence agency for months. The acronym stands for:
Strategic Hazard Intervention, Espionage and Logistics Directorate
Some folks have been up in arms about his casting because he seems to be based on the Marvel Ultimates Universe version of Nick Fury instead of the regular Marvel Comics universe. As it happens, the Ultimates version of Nick Fury was modeled after Sam Jackson, so now the circle is complete. :-)
Thanks to Scott for his sharp eye. :-)
