Damian Lewis and Helen McCrory have been raising money to feed NHS workers who are fighting coronavirus.
Lewis, who stars in HBO's Billions and upcoming film Dream Horse, and McCrory of Peaky Blinders and new ITV drama Quiz, have raised the money to feed NHS staff in London but will now roll the scheme, called FeedNHS, out to other cities in the UK, including Cardiff.
Lewis said the scheme will now be extended to Cardiff, Birmingham and Manchester.
"The public have been incredible," he said on the BBC's Coronavirus Newscast.
"I know a lot of people are feeling a bit cash-strapped at the moment, so they've been unbelievably generous.
"But it means we can now kick in with a second round of funding - which is essentially what we are trying to do - in order to take it to Birmingham, Cardiff and Manchester, because the virus will move through those city centres."
The couple, who have links with Wales through McCrory's mother Anne and Lewis' paternal grandparents, are currently isolating at home with their children.
McCrory said they had many friends in the NHS who were struggling to get food due to the hours they worked and restaurants and cafes had shut down.

The initiative has already sent out 6,000 meals which are from high street restaurants.
Restaurants who the couple have teamed up with so far include Leon, Dishoom, Wasabi and Tortilla with the aim to "get food to these people who were working such long hours and weren't able to".
The FeedNHS campaign was created by Lewis and McCrory with comedian Matt Lucas and John Vincent from LEON restaurants.
