The 47-year-old actor has been sharing plenty of pictures from "Furious 7's" sets. In the past few weeks he has shared pictures of himself with Walker, Jordana Brewster and Dwayne Johnson. Diesel plays Dominic Toretto in "Fast and the Furious'" latest instalment and his Facebook updates are keeping the fan interest alive.

"Furious 7" is Walker's last film. The actor passed away in a tragic car accident on Nov 30, 2013, while coming from a charity event. He played Brian O' Connor, a former FBI agent in the film, who is married to Dominic's sister Mia Toretto (Jordana Brewster). His character would be bid adieu in "Furious 7."

Meanwhile, one of the other actors of "Furious 7"," Ludacris also shared Walker's photo on his Facebook page. The close-up shot of the late actor is captioned as "Train your mind to see the good in everything" -Paul Walker."

Since Walker's untimely death, the film's cast have expressed their love for the actor. When the first trailer of the film was released on Nov. 1, his on-screen wife, Brewster, had said that the actor's death is the hardest thing she has gone through. "It's the most difficult, intense thing I've ever been through," Brewster told Cosmopolitan magazine, adding, "just yesterday, I had a moment where I thought, Oh my God, I'm never going to feel the way I felt when I hugged him.

Walker's brother Cody Walker is speculated to replace him on the screen, for the future instalments. Though in "Furious 7" he has been used as Paul's body double, he may have a full-fledged role in "Fast and the Furious 8" and an instalment after that.

"Furious 7" opens in April 2015. James Wan directs the film.
