In an interview last week, Hanks said he and his wife would be donating their blood.

Host Peter Sagal asked Hanks, 63, about life post-coronavirus and to which Hanks responded, “Well, a lot of the question is, ‘What now?’ You know?” Hanks said. “What do we do now? Is there something we can do? And, in fact, we just found out that we do carry the antibodies.”

“We have not only been approached, we have said, ‘Do you want our blood? Can we give plasma?’ And, in fact, we will be giving it now to the places that hope to work on what I would like to call the Hank-ccine,” the actor joked.
