Walker died in a car accident last November at the age of 40.
Diesel honoured Walker in a recent Facebook post, uploading a personal photo of Walker with his own twin brother, reports aceshowbiz.com.
Calling the photo “The Two Pauls”, Diesel wrote: “Pablo and my mother would have deep conversations… she claimed, that it was no accident that this on-screen duo has come to define brotherhood in Our millennium. You see… the other guy in the photo is also named Paul… and although they look more alike, he is actually my twin brother.”
“God knows we will need all of you to complete this intense experience called SEVEN. Though this may be one of the hardest things I have had to do in my career, I can’t help but to think… that it will also be the most significant,” he addressed his fans.
The production of “Fast and Furious 7” was halted after Walker’s sudden demise and it will be resumed on March 31.
