Actress Zazie Beetz has starred in the two highest-grossing R-rated movies ever - Deadpool 2 and now Joker. In 2o18, she appeared in Deadpool 2 as Domino, winning audiences over with her cool, collected demeanor and refusal to put up with Deadpool's sass. Earlier this month, she starred as Arthur Fleck's "love interest" in Joker, but her actual importance and involvement in the plot have been subjects of great debate.

In Deadpool 2, Beetz played a fairly large role, one that proved important both to the plot and to the future of that franchise. She will more than likely be back, too. In Joker, she was a tertiary character, living in the same apartment building as Arthur. Fans have speculated that either she or at her encounters with Arthur are simply a figments of the failed comedian's twisted imagination, but her character remains an important role in Arthur's life regardless. And thanks to the controversial film's box office success, Beetz can now add a second R-rated movie to her top box office earnings.

Deadpool creator Rob Liefeld shared a photo of Beetz in both roles to Instagram, proudly announcing that she has now appeared in the top two highest-grossing R-rated films of all time. Deadpool 2 grossed over $785 million worldwide and Joker just passed $800 million. The latter film doesn't appear to be losing much traction (if any at all), which is great for director Todd Phillips, lead Joaquin Phoenix, and Warner Bros. Early predictions pointed to a strong theatrical run but no one expected Joker to near a billion-dollar bow. Check out Liefeld's post below:

Few people had likely noticed that Beetz is the link between both of the highest-grossing R-Rated movies, and who better than Liefeld (along with Reynolds) to enlighten us. It's a seemingly pointless, "so what" observation, but it also indicates Beetz's status as an up-and-coming star in Hollywood. She's talented, funny, and a delight to watch onscreen. Her is career is definitely on an upward trajectory. At this point, who wouldn't hire her? Beetz has also appeared in Jordan Peele's The Twilight Zone for CBS All-Access and can currently be seen in Lucy In The Sky.

Now, technically, Deadpool 2 only reached the top spot at the box office for R-rated films because of its Christmas-themed, PG-13 release. While Joker, on the other hand, has reached the milestone in just the opening weeks of its release. Still, Beetz remains the constant between the two successful films, possibly proving Liefeld's theory that she is a key ingredient for success.
