On Monday, Jan 6, Diesel posted an 18-minute video that featured different moments between him and Walker. There are a few clips of the two on set of Fast & Furious as well as off the set. The video came with a caption that read, "A glimpse... of Dom and Brian... off screen."

Diesel also expressed the sadness he felt when he visited Walker's mother in December 2013.

"I thought they needed my strength, but realized when I got there and broke down before his family, that it was I who needed theirs. His mother hugged me and said I am so sorry... I said sorry? You're the mother who lost a son?... She said yes, but you lost your other half..." the post said.

The seventh installment is set to release in theaters on April 10, 2015.
