In the UK there was a tv series called “The Avengers”. Some genius in the marketing department decided we Brits might get confused between that forty year old show and the entirely unconnected Marvel superteam. The name of the movie was changed to “Avengers Assemble” and has remained such for the DVD release and tv broadcasts.
We also got the blade sticking out of Coulson’s chest digitally removed and no Joss Whedon audio commentary. I imported my Blu-Ray from the US.
That showed 'em.
