SAG Awards 2015: William H. Macy wins for ‘Shameless,’ isn’t entirely speechless

William H. Macy really wished he had taken the time to stash a piece of paper in his pocket on Sunday night.

The actor, who plays the drunken patriarch in the Showtime dramedy “Shameless,” won a Screen Actors Guild Award for performance by a male actor in a comedy series, then went backstage to enlighten reporters about a dreaded moment every actor faces at some point in his or her career.

“I’ve been doing this for a while,” the actor said at the Shrine Exposition Center. “One must write a speech.”

He elaborated: “There’s a moment every actor will understand: when you go home after an awards show and in your pocket you’ll find a speech you never get to deliver because you didn’t win.”

Well, the one time he didn’t put pen to paper worked out in his favor.

“I did not expect to win, so I didn’t write a speech!”

And as it turned out, the speech he did deliver was one of the night’s more colorful, including the line, “I’ve written so many great acceptance speeches that I never got to give, but not tonight. OK, to my fellow nominees ... forget it, you lost.”

It wouldn’t be the first time his doubts worked in his favor.

The actor, who won Emmys for acting and co-writing in the 2002 TV movie “Door-to-Door,” admitted he had some doubts about starring in series TV.

“I was afraid that I would not like playing the same character over and over,” he said, referring to his role as Frank Gallagher, the unfit parent whose addiction is so severe he once resorted to putting drops of alcohol in his eyes to get a fix.

“I was so wrong.”
