The campaign film (see link below) is designed to offer a unique insight into the hospital and follows the children, who are receiving dialysis treatment, as they play a Christmas game on the ward.
Great Ormond Street Hospital (GOSH) said the campaign was part of a fundraising drive aimed at corporate partners and companies. The hospital has created a campaign package that includes a bespoke 360-degree film narrated by Freeman, co-branded VR headsets, a shareable e-card, and PR and social media support.
Those interested are asked to donate to the charity, with all proceeds going towards research, medical equipment and refurbishment of the hospital.
Freeman, who is a Great Ormond Street Hospital ambassador, said: "Christmas is a precious time for families to be together, but some children at GOSH won't be well enough to go home. Staff at this fantastic hospital will make it as special as they can for all their patients, and watching this film really helps you feel like you are there in the moment with these brave children and young people.
"Having visited GOSH myself, as well as having been a patient there, it's an honour for me to help share this story and I hope lots of companies will dig deep to support such a brilliant cause this Christmas."
