'Avengers: Age Of Ultron' Reveals A 'Black Panther' Easter Egg And Two Bonus Feature Clips

Avengers: Age of Ultron is the gift that keeps on giving. As the supersized superhero saga heads toward a home video release, Marvel Studios has unveiled two bonus feature clips focusing on three exciting recent additions to the MCU: Ultron (James Spader), Scarlet Witch (Elizabeth Olsen), and Quicksilver (Aaron Taylor-Johnson).

Meanwhile, a fan has just unearthed an Avengers: Age of Ultron Easter egg which connects yet another new character, Ulysses Klaue (Andy Serkis), to a Marvel superhero we haven't even seen yet, Black Panther (Chadwick Boseman). Discover the Age of Ultron Black Panther Easter egg, and watch the Ultron featurettes, after the jump. 

First up, here's a clip (via USA Today) from a featurette about Olsen and Taylor-Johnson working with Spader:

And here's a clip (via Stitch Kingdom) from a featurette in which Chris Evans, Robert Downey Jr., Mark Ruffalo, and Serkis also get to gush about working with Spader:

Speaking of Serkis, we now have confirmation of the connection between Ulysses Klaue and Black Panther in the movies. In Avengers: Age of Ultron, we get a very brief glimpse of a file on Klaue. It goes by too quickly to read in the film, but an MCU fanpage was able to get a high-quality screencap and transcribe the text.

Ulysses Klaue was an assassin hired to take down T'Chaka at the Bilderberg conference in the case that he refused to negotiate Wakanda's resources including Vibranium. But, Klaue was also there personally, as the Panther killed his great-grandfather in the 19th century while this one was trying to annex Wakanda. He was paid ten million dollars for the kill.

T'Chaka, of course, is the father of T'Challa a.k.a. the Black Panther. In the comics, Ulysses Klaw (it's spelled Klaw in the comics) comes to T'Chaka's native Wakanda in search of Vibranium. When T'Chaka refuses to give up his nation's supply, Klaw kills him in front of his teenaged son T'Challa. The boy fights back, shattering Klaw's hand and earning a lifelong nemesis.

It's unclear how much of that story will make it into the movies. Notably, the Avengers: Age of Ultron file says only that Klaue was hired to murder T'Chaka, not that he actually succeeded. Kevin Feige has previously hinted T'Chaka is still alive in the MCU. "Today, pre-Civil War, post-Ultron I think [T'Challa] and his father are saying, 'A bunch of Vibranium just got out of here and wreaked a lot of havoc,'" he said in June.

For now, the file is just an intriguing detail. It'll be a while yet before we get the full story of the bad blood between T'Chaka / T'Challa and Ulysses Klaue in the MCU. Black Panther makes his MCU debut in Captain America: Civil War, set for May 6, 2016, before headlining his own solo film due out July 6, 2018.
