The 53-year-old Oscar-winning heartthrob made his name on TV almost 20 years ago, as Mr Darcy in period drama Pride And Prejudice, and has since been enjoying success on the big screen.
On Tuesday night, Firth was lauded with a GQ Men Of The Year gong for leading man, to add to his already-bulging trophy cabinet.
Speaking at the awards party in the Royal Opera House, the Tinker Tailor Soldier Spy and King's Speech star said he was tempted to make the move back to TV if he was offered a meaty enough role.
"I would definitely do TV, at the drop of a hat, if I was offered a good role," he said.
A string of established Hollywood stars, including Kevin Spacey and Halle Berry, have made the switch recently to TV, where drama is enjoying a golden age.
But Firth said: "I haven't really been offered anything."
He added: "I watch a great deal of TV, especially the US stuff."
