It was reported earlier this year that the US President had named the Showtime thriller as one of his favourite shows, requesting multiple DVD box sets.
"It's way cool that he's a fan," Danes - who plays Carrie Mathison - told The Hollywood Reporter. "It speaks to the relevancy of the show. It's hugely validating."
However, despite the show's themes of government corruption and terrorism, Danes claimed that Homeland is not a "particularly political show".
"It's not so preachy, which is, in some ways, why it carries its message so well," she suggested. "It's a psychological thriller that tackles big ideas."
Homeland star Damian Lewis (Nicholas Brody) previously revealed that he discussed the show with President Obama at a White House state dinner.
The series triumphed at last night's (September 23) Emmy awards, scooping six awards including a win in the 'Outstanding Lead Actress in a Drama Series' category for Danes.
