Marvel Studios and distributor Paramount have confirmed that they gave representatives of the international cinema market the option of releasing the movie under the title Captain America: The First Avenger or simply The First Avenger.
The majority of foreign distributors decided to utilise the Captain America name in order to take advantage of the Marvel superhero's global notoriety, but the Russian, Ukrainian and South Korean film industries have chosen to debut the film under the First Avenger title.
Reps for Marvel and Paramount offered no comment on reasons for the change in those three countries, but insiders told The New York Times that the decision was politically-motivated.
Additionally, Captain America: The First Avenger might not be screened in China at all, due to the nation's edict that no more than 20 foreign films be theatrically screened each year.
A final decision on a Chinese exhibition is still pending.
The DVD release of both Thor and Captain America: The First Avenger will reportedly feature two newly-filmed short scenes based around S.H.I.E.L.D. Agent Phil Coulson.
Captain America: The First Avenger is released in theatres on July 22 in the US and July 29 in the UK.
