Many have noted that the out-of-bounds area of the green-on-green tennis courts at the Rio Olympics look a bit like a green screen. But only one person had the wherewithal to take the time to actually use that space as a green screen and insert some ridiculous effects around the edge of the court.
Imgur user factionman aka Graham Hughes put together a few nice revamps of an Andy Murray tennis match, relocating it to the smokey interior of a volcano as though the players were just pawns in Dr. Evil's nefarious Olympics. The match was also relocated to space, the ocean, and the opening credits of Star Wars.
