The cast and crew of Fast & Furious 7, including Vin Diesel, Dwayne Johnson and Michelle Rodriguez, have paid tribute to late star Paul Walker in an open letter to mark the end of production on the movie.

The letter, posted on the official Fast & Furious Facebook page, reads: ''We made it. Today we completed the last shot in the production of Fast & Furious 7.

''We wanted to take this moment to express how thankful we are for your support. We felt the love and strength from our fans throughout this journey, and it's because of you that we got here.

''There was a time when we didn't know how we could go on, or even if we should. But we listened to you, and you inspired us not only to keep going but to try and make the best Fast & Furious movie yet.''

The letter continues: ''Our family is big and strong but it won't ever quite be whole again without Paul.

''All of us - those who've been here from the start and those whose first 'Fast' film is 7 - wanted to create a special film for him and for you. We believe we have.''
