In season 3 of the HBO series Newsroom starring Jeff Daniels, his character, Will McAvoy, is held in contempt of court for refusing to reveal the identity of a confidential source. When McAvoy is in the courtroom being questioned by the judge behind McAvoy on the wall is a copy of the Emanuel Leutze painting of Washington Crossing the Delaware.

The scene appears to be shot in an actual court room, not a set, so whether the painting was already there or was placed on the wall for the shot by the set coordinator is probably not discoverable by mere mortals.

Just a random factoid.
