Unfortunate Irony

If you look closely at the above picture of a double-decker bus destroyed by the London terrorist attacks, you can see that part of an ad for a movie called "The Descent" remains attached. A close up of part of this ad from another bus appears below. The ad reads, "Outright Terror...Bold and Brilliant." The film has been marketed with the tag-line "Face Your Deepest Fear." A most unfortunate coincidence.
