David Harbour took steps to make sure his Marvel Black Widow role didn't resemble Stranger Things

Entertainment Weekly

Harbour tells Jimmy Kimmel he was concerned that Stranger Things fans would see his Marvel role as too much of a coincidence, since the movie is also set in a Russian prison. "I had this long hair and this beard and I was big and I thought, 'I can't be the same guy with long hair and a beard in the same prison," Harbour said, according to EW. He admitted he sneakily took pictures of the Black Widow set and sent them to Stranger Things creators Matt and Ross Duffer, "making sure they didn't use any of the same colors as the set and making sure the looks were different and the outfits were different."
