Scarlett Johansson (Black Widow), Chris Hemsworth (Thor), Robert Downey Jr. (Iron Man), and Jeremy Renner (Hawkeye) who starred in the Marvel movie The Avengers just got matching tattoos. Their co-star Chris Evans (Captain America) also got a matching tattoo even though he wasn’t with the group at the time.

According to Robert, getting tattoos was Scarlett’s idea. He then shared the process through a series of Instagram posts.

It was only Mark Ruffalo, who plays the Hulk, who decided not to get inked.
