Maybe you can still deliver the basket to his home or have it sent. Enclose another card for the family. Express to them that you know how he enjoyed the movies. Just maybe he will be able to enjoy one last flick with his family by his bedside. If not, then maybe his family will find time after his passing to sit with those very movies and snacks and reminisce about the good times they had enjoying previous movies with their loved one. It may not be to late to express a wish to bring a bit of joy to him and his family during this very difficult time. It's never to late to let the whole family know you care.
It's a hard time for sure. Blessings and hugs to you.
