Shout Out / Ant-Man

• "No whistling. It's not The Andy Griffith Show. No whistling."^note A reference to the aforementioned show's theme tune.
• Yellowjacket and Ant-Man battle at one point on a Thomas & Friends Bachmann toy set.
• Scott and his crew segue into a discussion about Titanic as Scott is breaking into a vault made out of the same metal as the real RMS Titanic.
• Cassie has a plush toy of Flounder in her room.
• Shout-out to Marvel Studios' corporate owner, Disney: While disguised as a security guard, Luis nonchalantly whistles the theme song of "it's a small world".
• The suit being decades old and increasing the wearer's strength, Hank's medical condition meaning he can't use it anymore, the banter between Scott and Hank as Mission Control, and the plot involving an aging superhero trying to stop crime at his old company whose new CEO is a younger Corrupt Corporate Executive, bring to mind Batman Beyond.
• Alongside the fact that the Ant-Man suit resembles a Raygun Gothic version of Kamen Rider, the red-and-silver color scheme is similar to Ultraman, another famous Japanese superhero. And the colors of Hope's new Wasp suit◊ look rather like Ultraman Tiga's.◊
• If you listen carefully, Yellowjacket's lasers appear to use the sounds of the AT-AT walkers from The Empire Strikes Back, most evident during the train sequence.
• The placement of the "shrink" and "grow" controls of the suit is the same as the throttle switches for the jetpack in The Rocketeer.
• Cross's mooks shooting at Ant-Man while he is running through Cross's miniature model of the building is an allusion to Zoolander. The title for this section of the score? "Center for Ants." And then, the first trailer for Zoolander 2 played before some US screenings of Ant-Man.
• The bond between Scott and Ant-thony the ant and the latter's heroic but saddening demise calls Honey, I Shrunk the Kids to mind.
• The Quantum Realm sequence seems to be one big one for the "Jupiter and Beyond the Infinite" sequence from 2001: A Space Odyssey. It even features closeups of Scott's face in his helmet, same as with Dave in 2001.
• When Darren Cross reveals footage of the Ant-Man in action, he refers to the concept as "tales to astonish," the name of the comicbook in which Ant-Man originated.
• Garrett Morris' cameo is a shout-out to his portrayal of Ant-Man in an early Saturday Night Live sketch.
• A song by The Wiggles plays in the background when Hank arrives at Cassie's birthday party.
• During the end credits, the CGI wireframe perspective starts at an orbital view of Earth, then moves in closer and closer until we're looking at the cells of a blade of grass, then further still until we reach the quantum realm. Of course, Powers of Ten stopped at the angstrom scale, "the limits of human comprehension".
