His co-stars insisted on finishing the movie to honour him and they are continuing to pay their respects by posting a series of heartfelt messages on social media on the anniversary of the tragedy.

"This week is always rough for those of us who really knew him personally 14 years of laughter, hugs and love literally one of the nicest people on HUMAN FEET!!!!," Tyrese wrote on Instagram on Wednesday (30Nov16), along with a video montage of Paul.

"Nov 30th we lost an angel! Paul treated everyone with the upmost (sic) respect and went out of his way to make everyone feel like they mattered... I love and I miss you dearly. We simply ask of you prayer warriors around the world (to) pray for his daughter our niece Meadow Walker and his dear brothers CODY and Caleb and parents... May God rest your soul we hope we make you proud everyday!!!!!"

"I miss you and I love you every single day #paulwalkerforever," Jordana, who played Paul's onscreen wife, added, next to a picture of herself and Walker.

Another castmate, rapper Ludacris, also posted a picture of Paul from one of the movies with a caption reading: "Always in our heart", adding, "Gone but never forgotten."

And franchise star Vin Diesel posted a photo of the two leading men together on Facebook.
