She's the mother of the Shaw brothers.
“ | While doing an interview with Yahoo, Fast & Furious 6 and Beauty and the Beast star Luke Evans revealed that Mirren is playing his and Jason Statham's mother. Evans, who portrays Deckard Shaw's (Statham) younger brother Owen Shaw in the series, didn't provide any other details about Mirren's character, including a name. Evans also shared that there's still a possibility of Owen Shaw returning, as he won't be featured in the upcoming eighth franchise film.
“He’s in a military hospital because he’s the most wanted man in the world, but he’s got a very powerful brother, and he’s now got a mum as well, who’s played by Helen Mirren," Evans said. Earlier last year, Mirren admitted she was "very nervous" to be the newcomer on set for Fast 8, and that she's one of the people in the film who won't be driving. | ” |
