The flick, also starring Daniel Craig, Chris Evans, Lakeith Stanfield, Michael Shannon, Don Johnson, Jamie Lee Curtis, Toni Collette and Ana de Armas, was inspired by director Rian Johnson‘s love of Agatha Christie murder mysteries.

Katherine‘s other upcoming projects include Netflix’s Cursed and a possible role in Avengers 4.

Katherine Langford is officially part of the Marvel family.

THR, EW and many other sites reported over the weekend that the 22-year-old Australian actress was spotted filming scenes for Avengers 4 in an undisclosed role.

Now, THR is theorizing that it could be one of these roles: Kate Bishop, Death, Sersi, Clea, or even Veranke.

Many fans are set on the role of Kate Bishop for Katherine.

Kate takes over the role of Hawkeye after Clint Barton turns into Ronin after the events of Civil War.

We still think that Love, Simon was one of the most powerful and timely movies of the year, so we’re so glad to see the stars back together!

Nick Robinson and Katherine Langford joined forces while honoring the movie at the 2018 GLSEN Respect Awards on Friday night (October 19) in Beverly Hills, Calif.

The Love, Simon co-stars were joined by director Greg Berlanti and his husband Robbie Rogers to honor Twentieth Century Fox Films with the Visionary Award, which was accepted by Elizabeth Gabler.

Katherine‘s 13 Reasons Why co-star Tommy Dorfman also attended the event.

Greg and Robbie, as executives from The Berlanti Family Foundation, announced that they will give the foundation’s first gift of $1 million to support GLSEN’s efforts. The Berlanti Family Foundation is dedicated to improving the lives and personal stories of all LGBTQIA people and their straight allies through education, the arts, medicine and other social services.

Lili Reinhart is Betty Cooper, and Katherine Langford is Hannah Baker — but those facts could’ve been much different.

According to EW, Katherine was almost cast as Betty on Riverdale!

Camila Mendes revealed that Katherine was definitely in the running to play 1/4 of the core four.

“I remember when I met her, too — I never saw her act, but some people just have a personality that’s so genuine that I’m like, ‘I feel like you’re a really good actor,’” Camila remembered. “They have a presence. I had that feeling with her.”

“I remember we went out and we got falafel with a guy who was auditioning for Archie,” she recalled.

Camila adds, “It’s just so funny to think about that time in my life. I would have never thought in that moment that I would be here, and that she would be where she is. It’s crazy!”

Riverdale returns on October 10th on The CW.
