Fans were amazed when Vin Diesel recently announced the signing of MCU star Brie Larson for the upcoming "Fast and Furious 10". After Jason Momoa and Daniela Melchior, she is the next top-class newcomer for the second to last part of the series, and there is already a theory about who she might play. Via a range of forums and comments columns, fans are discussing Larson's yet-to-be-announced role, and many are of the opinion that she will star as Brian's sister. Following the then also unexpected news of John Cena in an unknown role, it turned out that he would be playing Dom's brother Jakob, so the assumption of the announcement of another close family member is not far-fetched. Besides, a tribute to the late Paul Walker's character in the upcoming two films is considered certain, so it could make perfect sense to introduce his sister. Apart from Larson, Momoa and Melchior, we will of course see old familiar faces such as Vin Diesel, Tyrese Gibson, Michelle Rodríguez, Ludacris and others again. "Fast and Furious 10" is scheduled for release on May 19, 2023.
