Ryan Reynolds and Jodie Comer front NHS Blood Donation campaign

Ryan Reynolds and Jodie Comer have urged people to register to give blood.

The ‘Free Guy’ actors appear opposite each other in the new movie about a bank teller who discovers he is actually a background character in an open-world video game, and he decides to become the hero of his own story.

Now, the pair have joined forces for an NHS Blood and Transplant video to urge fans to be “great guys” by donating blood.

Ryan compared blood donors to his character, who “always gives 100 percent” as Jodie explained that every donation can save up to three lives.

As an added bonus, fans can also show their support by downloading a digital Free Guy badge from NHS Blood Donation.

Health and Social Care Secretary, Sajid Javid, said: “Giving blood is a lifesaving act and I’m grateful to the stars of Free Guy for helping to share that message.

“There is a real shortage of male and young people giving blood so we particularly need hero donors from those groups to help us save more lives.

“It’s quick, easy and safe and I’d encourage everyone who is able to consider registering to donate today.”

And Zeeshan Asghar, National Partnerships Manager for NHS Blood and Transplant, said: “Just like Guy, blood donors choose to make a difference. They are everyday people who do something amazing – they save and improve lives by giving blood.

“The film’s themes of self-empowerment, being great and doing something good for others echo the motivations and rewards that our donors tell us about.

“We hope this exciting partnership with Twentieth Century Studios will inspire film fans and new audiences to be great guys by registering to donate.

“We’re delighted to have the support of Ryan and Jodie with their entertaining and engaging video about the lifesaving power of blood donation, which will help us to reach the people we need to become the donors of the future.

“The NHS needs 400 new donors every day to maintain the blood supply. We especially need more young people, black people and men to become donors. Please register today and book an appointment to start saving lives – your NHS needs great guys.”
