Paul Walker's untimely demise has left some of his "Fast and Furious" co-stars in utter shock. Kurt Russel, Vin Diesel and Tyrese Gibson have expressed immense sorrow on the loss of their dear friend and co-star.

Kurt Russell who has about to play a father to Paul's character in Fast 7 before his death told Entertainment weekly that though he got to spend very little time with Paul Walker, he developed an immense liking for him.

"That was a terrific guy," said Russell, adding, "I just met him on the [movie] and I was just very struck by how similar our lives are and how we looked at life. All the things he did outside of acting that he really enjoyed were similar to the things that I like to do. He was a hell of a good guy."

On Jan. 9, Vin Diesel posted an emotional video of Paul Walker and him on Facebook. Along with the video, Diesel wrote on his FB page, "There was always moments of child-like laughter...We had accomplished so much by 2013... P.S. The complexities of Brotherhood, and the painful void... of it's absence."

The 18-minute-video was the juxtaposition of behind-the-scenes of "Fast and Furious" movies. The good times spent by the actors together and the video also showed the kind of jokes shared by the two during the promotional events of the film. It showed the brotherly times they have enjoyed at car workshops and during a visit to Eiffel Tower.

Tyrese Gibson shared his emotions since the passing away of Paul Walker at "The Arsenoi Hall Show" on Monday. He referred to Paul as his best man saying in an interview: "I've never been depressed in my life, but I was very, very sad and down.It took me a minute to shake it."

Gibson further added that he took a 15-day trip to Dubai to get his smile back.

Paul Walker died in a tragic car crash on Nov. 30 and has been survived by his 15-year-old daughter, Meadow Walker.
