Oh yes. Sneaking an image of a rhinoceros into the movie so fans can sit there satisfied that they got some esoteric reference to the comics is the height of imagination.
They should concentrate and focus all their attention on actually making a decent movie this time. Leave the extraneous stuff like Easter eggs alone. Nolan and Raimi did it right.
Easter eggs, winks, nods, etc...are always lame, sometimes they're ridiculous and distracting and take you right out of the movie and they rarely serve any purpose to the story.
"Would you prefer yellow spandex?" ugh. So imaginative!
