When an actor has been attached to a film franchise since 2000 and has been the lead for 5 out of 6 movies, it is a big deal if he dies. People will go see Fast and Furious 7 out of respect and because of the media circus around it but, I doubt the studio will do 8 and 9. Its awkward now.
Fast and Furious was about Dom and Bryan. They've been the lead guys for 12 years now. And now one of them is dead. Its over

Trust me....the execs are losing their minds right now. They're sad that homie died but, they're definitely pissed they just lost about 2-3 billion dollars because 7, 8 and 9 was gonna print money.
