This is a spoiler free article…
The official Ant-Man twitter page posted this checklist of the Easter Eggs that appear in the film… or rather where to look for them. Now some of them are obvious like the Milgrom Hotel, the SNL actor, the bartender cameo and the song Michael Pena is whistling. But I've seen the movie twice and I don't remember a tattoo in the Yellowjacket suit scene and I never really saw the newspaper in the Ant-Thony riding scene. Guess I have a reason to go back and see it again.
Marvel's Ant-Man is in theaters now.
