Walker had completed most of his scenes before his death, but Comcast Corp-owned Universal Pictures was forced to put production on hold to figure out how to continue filming without him.

Walker's brothers stepped in for a few remaining scenes, which make a seamless transition in the completed film.

Walker's character Brian appears within the first 15 minutes as a settled family man, but he's restless for the underworld of crime, illegal street racing and heists led by Diesel's Dominic.

The plot, filled with one-liners, sees Diesel, Walker and co-stars Tyrese Gibson, Ludacris and Michelle Rodriguez take on a villain (Jason Statham) in cities across the world.

Despite Walker's death, filmmakers did not shy away from the turbulent storyline of "Furious 7" in which his character, along with the rest of the cast, are thrown into high-octane, life-threatening situations.

In one scene, all five drive cars out of an airplane and parachute into a mountain-top race.

The film ended with a tribute to Walker, closing with the words "For Paul" written in black against a white backdrop.
