Dream Cast

-Vin Diesel - Dominic Toretto
-Dwayne Johnson - Luke Hobbs
-Michelle Rodriguez - Letty Ortiz
-Jason Statham - Deckard Shaw
-Tyrese Gibson - Roman Pearce (I do think that he survived the plane crash, as we didn't see it a few seconds before it exploded)
-Chris 'Ludacris' Bridges - Tej Parker (I do think that he survived the plane crash, as we didn't see it a few seconds before it exploded)
-Nathalie Emmanuel - Ramsey (I do think that she survived the plane crash, as we didn't see it a few seconds before it exploded)
-Sung Kang - Han (I do think that he survived the plane crash, as we didn't see it a few seconds before it exploded, also you can't kill him again)
-Gal Gadot - Gisele Yashar
-Scott Eastwood - Little Nobody
-Jordana Brewster - Mia Toretto O'Conner
-John Cena - Jakob Toretto (I know that the director said he was dead, but this is Fast & Furious, how many characters escaped death and theres a strong chance to car was fireproof)
-Jason Momoa - Dante Reyes
-Alan Ritchson - Aimes
-Brie Larson - Tess
-Daniela Melchoir - Isabel
-Anna Sawai - Elle
-Kurt Russell - Mr. Nobody
-Luke Evans - Owen Shaw
-Charlize Theron - Cipher
-Helen Mirren - Queenie
-Leo Abelo Perry - Brian Marcos
-Henry Cavill (I could see him as the MI6 equivalent to Hobbs, who has a history with Deckard and is also an ally of Hobbs, also woundn't mind him squaring off against Dante or Aimes)
-Robert Downey Jr (as the a new villain who works with Dante and Aimes)
-Tego Calderon - Leo
-Don Omar - Santos

-My plot so far
For the story, Dom and Little B escape from the explosion and track down the plane crash, to find the crew, they are then rescued by Hobbs after traveling to Lisbon and seek reinforcements (Mr. Nobody, Little Nobody, Tess, Shaws, etc) to take down Dante and Aimes.
