Forrest Gump

Upon being placed in the All-American Team, Forrest gets the chance to meet President John F. Kennedy (appearing as footage of himself) at the White House. The scene then follows with Forrest reminiscing that some time after their meeting, the "nice young president" was assassinated and so was his younger brother, Robert F. Kennedy, years later, all while footage taken of President Kennedy and RFK right before they were both assassinated is shown at the same time.
