Shout Out / X-Men: First Class

• A neon sign at a bar says "Marv's Beer," a reference to writer Marv Wolfman.
• The Oxford pub, The Eagle. Which doubles as a reference to the Eagle Awards (named after the magazine) which the X-Men won in the 1970s and 1980s.
• At the end of the Argentinian pub massacre, Erik compares himself to Frankenstein's Monster to claim that he's looking for his "creator".
• The War Room is modeled after the one from Dr. Strangelove.
• The film's pulpy '60s setting and Tuxedo and Martini Spy Fiction elements are meant to evoke the mood of the early James Bond movies. The Creative Closing Credits are also partly inspired by the title sequence of Dr. No.
• The neon sign at the bar where they find Angel is "Atomic"—which is a reference to how mutants were called "Children of the Atom" in the comics. Also an example of Shown Their Work, since Las Vegas in the '60s and '70s was famous for the nearby nuclear tests, and everything was named after the famous atom; drinks, shows, and nightclubs.
• When Hank first demonstrates his power, he ends up hanging upside-down, right at Raven's eye level. Lampshaded, when Raven exclaims: "You're amazing!"
• During the training Charles and Hank bring up and discuss The Strange Case of Dr. Jekyll and Mr. Hyde.
• The second chapter of the "Children of the Atom" documentary on the Blu-Ray/DVD release is called "Band of Brothers." Both Michael Fassbender and James McAvoy appeared on the Band of Brothers miniseries.
