In the movie
Julie & Julia, we get in a rather grim moment of humorous juxtaposition to spot the poster for Corman's
Attack of the Crab Monsters on the wall of Julie's living room, right after she cooked Lobster for the first time in her life. Too bad for these creatures that this will likely be the closest they will ever get to see revenge for what is being done to them...
Less portentous is a framed ad for the movie
The Angry Red Planet we spot later, when they relax watching a comedy spoof on Julia Child.
