In 1973, a groundskeeper was laying the chalk, for the stadium's baseball field, when Magneto appeared, wearing his helmet and a new costume. The groundskeeper asked Magneto if he could help him, and the mutant replied with "No, you can't".
Then, using his powers, Magneto ripped the entire stadium off its foundations, and levitated it across Washington, and towards the White House. He then set the stadium around the White House as a barrier, in order to prevent any interference with his plot to assassinate the President, his Cabinet and the humans behind the Sentinel program. During this, the stadium sustained partial damage. Before the stadium was set around the White House, one of its lights fell, pinning Charles Xavier to the ground. Several Sentinels were also positioned around the perimeter of the stadium's roof, to prevent the police from interfering.
At the end of the film, a newspaper announces that the Stadium is to begin reconstruction.
- There are serveral anachronisms regarding RFK Stadium's appearance in X-Men: Days of Future Past:
- When Magneto arrives, the stadium is shown with a baseball pitch, with the groundskeeper laying chalk. Due to the film being set in 1973, RFK was not used as a venue for baseball games as the Washington Senators (the baseball team that played at the stadium) had left for Texas two years prior & the stadium would not host another baseball game until 2005. Also in 1973, RFK hosted soocer games after the Senators left.
- One of the stadium's billboards promotes the soft-drink Mountain Dew. The billboard features the Mountain Dew logo used in 1980.
- In the film, the lower seats in the upper ring of the stadium are purple. These seats were light blue in 1973, and were replaced by purple seats during the early 1990's.
- The newspaper that announces the stadium's reconstruction at the end of the film is called The Washington Senator. This is a possible reference to the Washington Senators, the baseball team that played at RFK until 1971.
- The stadium originally opened in 1961 as the District of Columbia Stadium, but in 1969 it was renamed in honour of Robert F. Kennedy, the 64th United States Attorney General & younger brother of President John F. Kennedy.
