The late Paul Walker's younger brothers have stepped in to help complete scenes for 'Fast & Furious 7'.

Caleb and Cody Walker have signed on to shoot the remaining scenes featuring the star's character, Brian O'Connor, for the forthcoming film - which is tipped to be released in April 2015 - following the death of the hunk in November last year.

A note on the movie's official Facebook page stated: ''The Fast & Furious saga is about family. Our family experienced an unthinkable shock in November. We had to take time to grieve Paul, the brother we love and lost, and to figure out if we should move on with our film.

''We came together and all felt the only choice was to continue. We believe our fans want that, and we believe Paul would want that too. Paul had already shot his dramatic scenes and most of his action for 'Fast & Furious 7,' and it's among the strongest work of his career.

''We have resumed shooting and now welcome Paul's brothers, Caleb and Cody, into our Fast family. Caleb and Cody are helping us complete some remaining action for their brother and fill in small gaps left in production. Having them on set has made us all feel that Paul is with us too.''

Walker died alongside his friend Roger Rodas, who was driving when the Porsche Carrera GT they were travelling in lost control and crashed in Santa Clarita, California on November 30, 2013, and investigators released a report that concluded excessive speed caused the accident, as there was no evidence of mechanical failure.
