Dream cast for Alex Rider saga remake

Who would you cast in a new Alex Rider saga? Here's my list

Alex Rider- Dane DeHaan. Yes he's old, but looks much younger than he actually is and has played teenagers before, like in Chronicle. He's also a dang good actor.) Evan Peters would be my second choice, although he has the same problems Dane DeHaan has.

Alan Blunt- Tim Pigott-Smith. This guy is the perfect Mr. Blunt! He is monotone enough to fit the part but never is boring or monotone

Yassen Gregorovich- Jake Gylenhaal. He would be an absolutely perfect Yassen, would just need some voice lessons to pull off the accent.

Jack Starbright- Jessica Chastain. Serious acting chops, and also looks like how I imagined Jack in the books. She might not accept a role that is pretty minor until the final book though.

Mrs. Jones- Judi Dench. Yeah yeah, kinda cheap to cast M from the James Bond movies into M's equivalent in the Alex Rider universe, and would be really weird considering James Bond is mentioned in the Alex Rider universe, but honestly she is the best fit for the role.

Sabina- Honestly you could pretty much put any early 20's british actress in this role and it'd be ok with me.
