According to Deadline, Tatiana Maslany (Orphan Black) has been cast as the lead in the Disney+ She-Hulk series as the titular character.
Previous news stated Kat Corio would direct several episodes of the series, including the pilot episode. Writer Jessica Gao (Rick and Morty) has been hired to lead the writers room for the series.
The last major character to be co-created by Stan Lee, She-Hulk is Jennifer Walters, an attorney and cousin of Bruce Banner, aka The Hulk. An emergency blood transfusion from her cousin gives Walters her powers, but unlike Banner/Hulk, She-Hulk was able to keep her intelligence and personality when she Hulked out. (Deadline)
She-Hulk is currently under pre-production, but due to events of the COVID-19 epidemic, the start of production is currently unknown.
