Sterling K. Brown has revealed filming Black Panther is a bit of a covert operation in itself.

The This is Us actor compared Marvel's preventative plot-leaking measures to something that could have walked straight out of a Mission: Impossible movie.

Well, no one likes spoilers, right?

"Being in a Marvel film is the pinnacle of secrecy training," Sterling told The LA Times.

"You get the script, but not a hard copy. And then, like, it dissolves. Like, it's Mission: Impossible. The link self-destructs.

"Then you get to set and they give you your sides [scenes] for the day, and when you finish shooting, you turn your sides in.

"And if you don't turn your sides in — 'cause I forgot mine at the hotel one time — they follow you to your hotel to get your sides.

"And then you sign out. They ain't [playing] around."

Sterling plays N'Jobu, a character from T'Challa's (played by Chadwick Boseman) past in the movie, and he's just the tip of a very starry supporting iceberg.

Indeed, the movie - which will hit theatres next year - also welcomes The Walking Dead's Danai Gurira as Okoye, Lupita N'yongo as Nakia and Oscar winner Forest Whitaker as Zuri, an 'elder statesman' of Wakanda.

Also getting involved is Get Out star Daniel Kaluuya as T'Challa's confident W'Kabi, as well as the legendary Angela Bassett (who you may recognise from American Horror Story, What's Love Got to Do with It) who will play appear as T'Challa's mother Ramonda, the queen mother of Wakanda.

But you know, she's a queen already, so it shouldn't be much of a stretch.

Black Panther is released in UK cinemas on February 9, 2018, and in the US on February 16, 2018.
