In case you didn't know or just never noticed, the stadium shots in Major League II were filmed in the Fall of 1993 at Camden Yards. The filmmakers were looking to create authentic crowd scenes for the film and were in the need of some extras to fill the stadium. Local radio stations promoted the opportunity of appearing in a major motion picture and lured them with chances at raffle prizes that ranged from Sony Walkman's to brand new automobiles. The advertising worked as 15,000 Baltimoreans showed up to learn how to become movie actors.
In order to make Oriole Park at Camden Yards look and feel like the home ballpark of the Cleveland Indians, many things had to be done. The extras who showed up were given Cleveland Indians attire and many even had their faces painted. The outfield walls which are green were covered with blue and retired numbers of players were added. The Eutaw Street Bleachers were filled with cardboard people and all Oriole logos had to be covered up (or as best as they could).
As someone who has been going to Camden Yards their whole life, I find it funny every time Major League II is on TV as I can always see the things authentic to Baltimore that would not be in a stadium in Cleveland.
Below are a few clips from the film that show geographic mistakes of things would only be at Oriole Park at Camden Yards. If you are just learning that Major League II was filmed at OPACY, I would highly suggest re-watching the film as these are only a few of the noticeable landmarks of the stadium.
