It’s been a few months since the release of Avengers: Age of Ultron, but Marvel isn’t done providing us with new materials from the film. The blockbuster sequel is hitting DVD and Blu-ray in a little over a month, but you can check out a clips from one of the bonus features right now — as well as a little Black Panther easter egg you might have missed the first time around.

USA Today revealed the video above, featuring Elizabeth Olsen and Aaron Taylor-Johnson — aka Scarlet Witch and Quicksilver — talking about working with their big bad co-star, James Spader. The other clip, below, comes from Stitch Kingdom, and features Chris Evans, Robert Downey Jr., Mark Ruffalo and Andy Serkis also talking up Spader and his talents. You can also see Spader in his mo-cap gear (which looks like a comfy get-up with lots of padding) filming some Ultron scenes.

And if you happened to miss the Black Panther easter egg in Age of Ultron, the MCU fan page on Facebook (via Slashfilm) picked up this screen shot of a file on Serkis’ Ulysses Klaue character from the film:


Here’s 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.

Klaue is a villain featured in the Black Panther comics, but this file confirms their connection in the MCU proper — T’Chaka is T’Challa (Black Panther)’s father, and they both hail from Wakanda.

We’ll see Chadwick Boseman’s Black Panther on the big screen when Captain America: Civil War hits theaters on May 6, 2016. The Avengers: Age of Ultron DVD / Blu-ray hits shelves on October 2.
