Another day, another piece of interesting news. It has been recently stated that one Banksy original rat graffiti was painted over by Christopher Walken during the shooting of the TV show The Outlaws. It wasn’t, though, an attempt to mock the iconic contemporary street artist. Official Banksy sources confirmed that the anonymous mural painter sprayed his trademark rat on a wall specifically for the set. That’s how he left the mark, a sort of Easter egg, in the final episode of the show.
