Paul Walker’s brothers are trying hard to keep his legacy alive by helping with the production of Furious 7. Paul’s brother, Caleb and Cody opened up about their experience at the set with Entertainment Tonight and shared the second annual Game4Paul fundraising campaign which will ultimately benefit the late star’s disaster relief nonprofit organization, Reach OutWorldWide.

The brothers said about the film that it help them in lightening the grief and pain they suffered. Caleb said, “We got to understand more about Paul, and what he was all about. We had to share Paul with a lot of people, in a weird way. He was gone a lot, he was filming, so we missed him. Sometimes at the holidays he wasn’t always there, you know? He tried.

We’d see him on set, we visited a few times, but to kind of get that closure, and understanding of Paul was really special.” Caleb recounted, “We had a really good talk with Vin Diesel. Vin is like the godfather, he really is, and he kind of became our godfather in a weird way. He obviously knew Paul so well, he shared things with us that Cody and I didn’t know.” He added, “Paul kept a lot of things about work kind of quiet with his family and friends, and so we were able to learn some things through his co-stars.”
