apropos of nothing

I drove past the Music Hall Theater in Beverly Hills the other day.  They’re showing Sugar and Moon and their marquee looked exactly like the above image, the two movies’ posters jammed together for a display.

Had I not already seen Moon, I would have guessed that they were showing one movie called Sugar Moon.  “One’s black, one’s white.  One’s big, one’s small.  One’s close up, the other is far away.  One’s in front of a bridge, the other is in front of an op-art design.  One carries a duffle bag, the other carries an astronaut helmet.  Each prefers his title in the lower left-hand corner.  Together they fight crime.  Sugar Moon.”
