"It's nice to see colleagues," he told reporters after winning the award for best actor in a drama for Showtime's Dexter, "and for me to show [people] I am doing fine."
The very private actor, 38, only revealed his battle with cancer four days ago, and said he originally wanted to keep his condition a secret.
"I had every intention of keeping it quiet, but because award shows were imminent, I had to make a statement," Hall said. But, he added, that it was nice to be able to make the statement when his prognosis was good.
In his fight against cancer, Hall says he's been staying positive and gaining a new perspective on the important things in life. "I like to think I have a good head on my shoulders," he said. "I have never been less susceptible to [having a big head] given the more down in the trenches stuff I have been considering."
Hall's Dexter costar and fellow Golden Globe winner John Lithgow had nothing but praise for Hall, calling him "Tremendous … The man truly deserves [to win]," said Lithgow. "Michael is a stupendous actor."
Hall wore a dapper suit and a black designer Japanese cap to cover his head. He joked about the look, saying, "It's nice to have an excuse for accessorizing."
