Fast and Furious 7 stars Michelle Rodriguez and Tyrese Gibson are struggling to keep a smile on their faces as they promote their new film without Paul Walker.
Promotional press tours for Furious 7 have already begun ahead of its 3 April release date, but Rodriguez and Gibson have mixed emotions as they travel the world without Walker by their side.
Gibson told Access Hollywood, "It's the most uncomfortable press junket any of us have ever done, because obviously... it's my first time ever being a part of a movie where someone I know and love is on the poster and they're not there.
"It's almost like, just release the movie and we'll stay at home, because to be smiling on red carpets or doing interviews is hard," he added.
Rodriguez who plays Letty Ortiz in the movie said, "Pretending everything is just fine and dandy... it's not real, you know?"
Rodriguez and Tyrese Gibson also honoured Paul's brother Cody at the Noble Awards held at the Beverly Hilton Hotel, for carrying out the work Paul did with the humanitarian relief organisation he founded, Reach Out Worldwide.
Cody choked back tears as he accepted the prize from Gibson and Rodriguez.
Cody Walker told Access Hollywood, "What this means for us is that so many other people loved Paul and loved the work that he was doing. And we just feel the love by being here and being a part of this and being honoured by this. It just makes it super special."
The two siblings, Cody and Caleb joined the Fast and Furious cast to act as stand-ins for their late brother to help complete filming on Furious 7.
Caleb acknowledged he is glad to be doing the difficult press tour with Cody, saying, "There have been mixed emotions during filming and press has been so intense, but you feel it's nothing but positive energy.
"It's been challenging, but being able to spend more time with Cody has meant more now than ever."
Paul Walker was killed in a car accident in November 2013, in the middle of filming for the seventh instalment of the blockbuster franchise.
