The self-deprecating Englishman need not worry about future doors being opened for him. Following his second award for his role as the stammering King George VI, Firth is the odds-on favorite to win the Oscar.
Firth's road to the Oscars is paved with the love of two women as much as it is his iconic film roles. After accepting his SAG trophy, the 50-year-old actor took a moment backstage to send a text message to his wife, Livia Giuggioli, who was back home in England.
Giuggioli, an Italian producer and mother of their two boys, Luca and Matteo, will most likely be cheering Firth from the audience at the Academy Awards on Feb. 27.
Meanwhile, actress Meg Tilly, Firth's former love and mother of his 21-year-old son Will, is likely to be cheering him from her remote cabin deep in the woods outside Vancouver, Canada.
Following Firth's Golden Globe win for "The King's Speech," Tilly, now 50, wrote on her blog: "Our happy hats off to a member of the family. We are so pleased for you! Hearty jigs are being danced. Tonight...we shall all lift a glass of wine to toast your continued success! Jubilant hugs and kisses from all of us. Onward and upward!"
Ironically, Firth, who has made a career of playing the reluctant lothario, might not be where he is today if he had chosen to stay with Tilly in their remote part of the world. Both quit acting after Will was born. Firth chose to return to the craft but Tilly did not.
"Meg Tilly has always been a mysterious figure," Stacey Wilson, associate features editor of The Hollywood Reporter, told ABCNews.com. "It kind of makes sense that two very private people found each other."
"Colin has always struck me as someone not terribly comfortable with the limelight," said Wilson, who has interviewed him. "He's the consummate Brit -- withholding, terribly polite and very serious."
When Firth met Tilly on the set of the period drama "Valmont" in 1989, he was a relative unknown and she was a Golden-Globe winning and Oscar-nominated actress for her role as a nun who discovers she's pregnant in "Agnes of God."
Tilly, who was also known for her memorable role as the girlfriend in "The Big Chill," was divorced with two children when she met the 29-year-old Firth.
According to Britain's Daily Mail, it was love at first sight. "It is a very special movie for me," Firth is quoted saying at the time. "I was probably in love with Meg from the moment I met her, but it took her a while to be convinced."
The couple moved to her home in Los Angeles before relocating to a log cabin on five acres, an hour north of Vancouver.
"It was in thick woods on the side of a mountain, and it felt like there might be no one for miles and miles," Firth said.
Their son Will was born in 1990, and for two years they turned away acting roles to stay close to home. Firth occasionally took odd jobs as a carpenter to keep the family afloat. But eventually, the call to act became too strong for him to ignore.
When Will was two, Firth returned to London to resume acting. When he wasn't working, he'd return to the cabin and family life.
