“Fast & Furious” star Paul Walker would have turned 43 on Monday, Sept. 12. Although he’s already gone, his presence is still felt by his friends and family, including his younger brother Cody Walker, who’s now pursuing a career in acting shortly after Paul’s death.

On Monday, Cody shared a touching Instagram post, expressing how important Paul was to his life. “To the man that influenced so much of my life and who I am. I love and miss you everyday, Pdub. Happy birthday,” Cody wrote on the social networking site, alongside a throwback photo of the two.

After Paul died in a single-vehicle accident on Nov. 30, 2013, Cody stepped in as a body double for his brother in “Fast & Furious 7,” which was still filming at the time of Paul’s death.

In an interview with E! News ahead of the “Fast & Furious 7” release date, Cody admitted that he was initially doubtful of joining the seventh installment of the action film series.

“It’s an experience that I was very hesitant to commit to, but I’m really glad I did,” the 28-year-old actor said at the time. “I met a ton of really amazing people and made several life-long friendships. It was an absolute roller coaster throughout the entire process — lots of tears, lots of laughs.”

Since Cody had no prior acting experience, filming scenes for the movie was definitely a challenge for him. Good thing, his brother Caleb Walker was with him all throughout the process.

“I don’t think either one of us could have done it without the other,” Cody said of Caleb who also served as a stand-in for Paul. “It brought us closer than ever at a time where we both really needed it. That is probably the single most important part of making this movie.”

Although Cody was a trained paramedic, he decided to continue Paul’s legacy by pursuing a career in acting. This was confirmed by Paul’s former manager Matt Luber to New York Daily News in April 2015, saying: “(His acting career) is in its beginning stages. He’s open to all types of roles.”

Three months later, Variety reported that Cody landed a role in the World War II film “USS Indianapolis: Men of Courage,” which stars Nicolas Cage, Tom Sizemore and Thomas Jane, among many others. The Mario Van Peebles-directed film opened in theaters last Sept. 1.
