"Fast & Furious 7" has gathered much steam since the sad demise of its main lead Paul Walker. The film is set to release on April 10, 2015 and there is a lot of anticipation as to what would be happen to Walker's character. Walker played Brian O'Connor in the film and the reports are rife that his character would have happy ending and not a sad departure as earlier rumoured, according to reports by Christain Post.

According to media reports the makers of the film have made necessary changes to the script of the film and Brian would retire from Fast gang in the end of the film.

Cody Walker who is playing Walkers body double was spotted shooting a happy scene with Jordana Brewster on the sets. Jordana is Paul's on screen wife and from what it seems Paul' character would bid a "bittersweet" goodbye to the rest of "Fast & Furious" cast.

"I'm sure it will be very bittersweet," Brewster told to E! News. "We all just want to honor Paul going back. I'm looking forward to being back with the Fast family, but there's definitely a key element missing."

Paul Walker died in a car crash on Nov. 30, 2013. The principal photography of the film was finished before Walker's death. The production was stalled for few months and was restarted as Paul's brother, Cody and Caleb agreed to step in.

Meanwhile, Vin Diesel who plays Dominic Toretto, recently shared a touching video of Walker on his Facebook page. The video was to honor Walker who would have turned 41 on Sept 12. The video showed cast and crew of "Fast & Furious" celebrating Walker's 40th birthday.

The video received more than million likes and thousands of share with comments from the fans including "We miss you Paul" and "Happy Birthday." "Fast & Furious 7" would be Walker's last film. The other cast of the film includes Vin Diesel, Dwayne Johnson, Ludacris, Jordana Brewster and others.
