According to THR actress Danai Guira (Michonne) will leave TWD after season 10.
Under her new deal, Gurira will return in a limited capacity — described as only a handful of episodes — that will be interspersed throughout season 10. The actress, playwright and social activist will then likely segue to the three Walking Dead movies that AMC is planning with former leading man Andrew Lincoln. The latter has played the central role of Rick Grimes since the pilot and departed in the first half of season nine.
Fans will no doubt see this as another nail in the coffin (pun intended) for the long-running zombie apocalypse TV show. Earlier in the current season the drama lost its lead Andrew Lincoln and a major supporting player Lauren Cohan. However, Lincoln will reprise his Rick Grimes role in a trilogy of made-for-TV movies and Cohan who plays Maggie is expected to get her own spin-off show.
