Fans and close friends of actor Paul Walker, who will star posthumously in the upcoming 2015 movie 'Fast and Furious 7,' are still mourning his death a year ago on Nov. 30, taking to social media to express their eternal grief.

On one of the movie's fanpages, a photo was posted showing Walker clad in a black suit, standing beside a car. Another photo of the actor was posted, with a puppy resting on the actor's lap.

"One year but we will never forget you. Always in our hearts. Paul Walker a great man with a big heart, an exceptional heart," said one of the captions on the Fast and Furious postings.

Close friend and co-star, Vin Diesel also used Facebook to remember his late friend, saying that Walker was the one who inspired him to be a better father for his daughter, Alpha Angel.

Diesel shared that her daughter was born while the two of them were filming a scene for the fourth Fast and Furious film, and that it was Walker who encouraged him to go inside the delivery room to cut the cord.

"He was an important part of my transition into fatherhood... that healthy family member, with the most positive outlook on life..." wrote Vin Diesel last Monday, on Dec. 1.

Diesel added that Walker used to babysit his daughter and had long talks with her mother regarding fatherhood.
