I spotted the Black Widow Blu-ray in a store today, and it is simply a standard blue plastic box with a black cover with Black Widow wearing black on the cover.
While this is fine, i though Disney might have add a card slipcase featuring the white snow suit art, which feature in many of the posters.
Seems Disney are off the ball lately.
The 4K Blu-ray features a slightly more interesting cover, with a white backdrop.
The Zavvi Exclusive 4K Ultra HD Steelbook
I'm not sold on that either, as it simply looks like the poster with a Photoshop effect applied.
Atleast they went with the snow suit.
