Everyone in the "Fast and Furious 7" movie is very good at intriguing fans about the last Paul Walker film. Renowned "Saw" director James Wan admitted in his interview with Collider that the new "Fast" title will be a shocker.

"I think the final product will surprise a lot of people. It's that hardest film I've ever had to make but it's also the one I'm proudest of," Wan told Collider.

Being the horror film master that he is, expectations for the film are soaring already.  The director's genius can be expected to shine in the upcoming high-status film.  Wan's transition from low-budget films to a high-budget one did not seem to be much of a bother.

"It doesn't matter how big or small your film is. You still don't have enough money. You don't have enough time to shoot it. When you're making a bigger movie, you have much bigger set pieces that require more time and more effort and more people," Wan revealed.

Before the movie was shaped into another highly-anticipated "Fast" title, the production and the cast and crew had to go through so many struggles. In the middle of the "Fast 7" production, main actor Paul Walker was tragically killed in a car accident. The loss was already excruciating enough. The autopsy reports of the beloved actor showing that he was still alive after the crash hurt them all the more.

The filming was then brought to a standstill. During the tough time, the cast and crew had to finish the film without their friend and with heavy hearts. They instead had to shoot scenes with Walker's character still around but without the actor's actual presence. The fallen actor's brothers Cody and Caleb Walker did the remaining scenes involving his character.

In "Fast and Furious 7," fans will get to watch Paul Walker in action again together with Vin Diesel, Jason Statham, Dwayne Johnson, Michelle Rodriguez, Jordana Brewster, Tyrese Gibson, Ludacris, and Lucas Black.

Walker's close friend and co-star Vin Diesel informed fans through Facebook that the trailer set for a Nov. 1 release will honor the late actor. "Fast and Furious 7" will be released on Apr. 3, 2015.
