Scarlett Johansson and Amber Heard
Both of these actresses are important characters in their superhero universes. Scarlett played the deadly assassin Natasha Romanoff (Black Widow) on the Marvel Cinematic Universe (MCU), and Amber portrayed Mera, Aquaman’s love interest Mera on DC Extended Universe (DCEU).
These blood bombshells have so much in common that some people speculate that Amber sometimes imitates Scarlett. In 2012, Scarlett wore a black gown with a criss-cross back at the Golden Camera Awards in Berlin. On the Metropolitan Opera Gala in NYC, Weeks after, Amber was spotted wearing the same black gown and an almost identical look as Scarlett.
