Despite the recent reports of Vin Diesel and Dwayne 'The Rock' Johnson feuding, which could be a WWE stunt, the brothers claim that Diesel has been a godfather to them. While Fast and Furious 7 bid farewell to Walker's character in a touching way, Diesel, Caleb, and Cody have discussed bringing Brian O'Conner back. Diesel wants to bring back Walker's character as a way to let the film's fans know that Walker is still out there, stated Caleb.
It's unknown whether Brian O'Conner will make an appearance in Fast 8, which is scheduled to be released on April 14, 2017. Diesel also revealed that more high-octane movies would be released in the future. Previously, Diesel revealed that Fast and Furious 9 would be released on April 19, 2019, while Fast and Furious 10 would be released on April 2, 2021.
With Helen Mirren and Charlize Theron set to make appearances in Fast 8, as well as an incredible list of vehicles, the upcoming movie should be more of what fans have come to love from the franchise.
