 In February 2012 , Disney announced that the film 's title would be changed in the United Kingdom to avoid confusion with the British TV series of the same name , as well as its 1998 film adaptation . This led to confusion over the film 's actual title . Empire magazine reported that the film would be titled Marvel Avengers Assemble while The Hollywood Reporter said that it would be called simply Avengers Assemble . Marvel 's UK website refers to the film as Marvel 's Avengers Assemble , although David Cox of The Guardian , in arguing that it was one of the worst film titles ever , considered this to be an error in the production notes , albeit grammatically clearer . According to the British Board of Film Classification and the Irish Film Classification Office , the title is Marvel Avengers Assemble . Frank Lovece in FilmFestivalTraveler.com addressed the discrepancy , writing , " The Avengers — formally titled Marvel 's The Avengers onscreen , though no apostrophe @-@ s appears on the posters ... " Producer Kevin Feige said there are only two words in the UK title , one more than in the U.S. title , and stated that " decisions like that aren 't made lightly and there are lots of marketing research , lawyers and things that get into the mix on it " .
