After all theres no Rock for F9 so they gotta get someone else big.. otherwise no big hook for ppl to come see (also when last time RDJ played a villain? Actors love playing villains especially when they usually only do good guys.. And he probably looking for something else big to do after MCU and F&F does attract big names you think wouldn't do it but they do as it so big)
