Steinfeld, who earned an Oscar nomination and was launched to stardom with 2010's True Grit, is already starring in a series for a rival streaming service, Apple. Sources tell THR that Apple has not cleared the actress for anything as of yet as she is attached to star in Dickinson. That show — which is not a close-ended limited series — will likely be among the first originals to be included in Apple's forthcoming streaming service.

Steinfeld also headlined the Transformers spinoff Bumblebee last year, and she is also already a member of the Marvel family. The actor voiced Spider-Gwen in the Oscar-winning animated film Spider-Man: Into the Spider-Verse, which is part of Sony's separate universe based on Spider-Man characters.

Hawkeye, which is expected to bow in fall 2021, is one of multiple Disney+ series in the works at Marvel Studios starring its big-screen talent, including Falcon & The Winter Soldier, WandaVision and Loki. Marvel is also going to introduce new heroes to headline future Disney+ shows, with She-Hulk, Moon Knight and Ms. Marvel all in the works.

Former Mad Men writer Jonathan Igla will write and executive produce Hawkeye.

While a number of Marvel's movie stars are appearing in its shows, Steinfeld marks the biggest new addition to its Disney+ roster to date. She is repped by CAA.

Variety was first to report the casting.
