And on Friday he joined other well-wishers in expressing his happiness about the marriage.
"I'm very happy that I can now legitimately call him my son-in-law, this wonderful fellow who I love, and that they're very happy," Voight, 75, told ITV's Good Morning Britain. "The kids must have had a wonderful time at the wedding because they all had their things to do."
Of the wedding, he adds: "It must have been very beautiful. I'm very happy for them."
The couple are already moving on with the next step, mixing honeymoon with work as they prep for a movie on Malta in the coming weeks.
"She's working now with Brad, and I've got a couple of things to do, too," Voight said. "But as soon as we can, we'll get together – it's going to be exciting."
