Vin Diesel recently induced nostalgia as he shared a touching photo of himself with late friend and co-star Paul Walker. The actor posted the snap to his Facebook account in which he can be seen sharing a hearty laugh with Walker. The two actors appear to be leaning on a blue coloured railing as Ludacris is seen standing behind them. Diesel is dressed casually in a t-shirt and a pair of jeans whereas Walker has donned a black jacket over his shirt.

The actor captioned the photo as "At undefined," and it was shared more than 17,000 times by the avid fans of the star. Diesel has been updating his Facebook page regularly. Along with his personal snaps he has been sharing stills from his upcoming film "Fast & Furious 7." The actor will be seen reprising the role of Dominic Toretto in the film. He will be going in search of Han's killer, who was killed in "Fast & Furious 6."

The film is reportedly close to actor's heart as it is during its shoot that he lost his close friend Walker. The 40-year-old actor passed away in a tragic car accident while coming from a charity event. His car hit an electric pole and burst into flames. His friend and business partner Roger Rodas also died in the accident. Both of them reportedly succumbed to fire injuries. Before his sudden demise, Walker had completed most of his scenes for "Fast & Furious 7." His brothers Cody and Caleb Walker have finished his remaining ones.

Diesel has said in many interviews that "Fast & Furious 7" was one of the toughest films of his career as he had to finish it without Paul, reported Access Hollywood. Paul's character Brian O' Connor will retire in the film. It has been reported that Cody will be playing a full-fledged character in the upcoming "Fast & Furious'" films. "Fast & Furious 7" is scheduled to be released on April 3, 2015. The film's official name is "Furious 7." It also stars Dwayne Johnson, Jordana Brewster, Nathalie Emmanuel, Kurt Russell, Michelle Rodriguez and others. James Wan of "Saw" and "The Conjuring" fame has directed it.
