Paul Walker’s career was booming at the time of his death, and his work is still generating big bucks for his estate and his reps.

Walker was famously filming “Fast & Furious 7” when he tragically died, but he had films in the can including the Luc Besson-written “Brick Mansions” and indie action movie “Hours.”

A Hollywood source told Page Six that Walker’s manager of 18 years, Matt Luber of Luber Roklin, is still owed $1 million in commissions from projects that Walker was working on or had completed. The actor was also set to star in the Nicholas Sparks adaptation “The Best of Me” and a new installment of Fox’s “Hitman” franchise, “Agent 47.”

However, Luber told us the total was likely less than $1 million. He said, “It’s sad, very sad, the films we couldn’t do.” Walker was replaced in “The Best of Me” by James Marsden and in “Agent 47” by Rupert Friend.

In addition to money flowing to Walker’s estate, his charity Reach Out WorldWide is getting a portion of proceeds from home entertainment sales of “Fast & Furious 6.”
