The ITV drama stars Michael Kitchen as a detective working in Hastings before, during, and after the Second World War.
Writer Anthony Horowitz recently said on his website that the show could return in 2013, though he explained that nothing is "definite".
Cast member Julian Ovenden has now also revealed that talks to bring the show back for an eighth series are taking place, The Sun reports.
"It's a possibility," he said. "And it will be interesting to see what happens as the war ended in the last series. So it's an interesting conundrum."
Other stars who appeared in Foyle's War include Honeysuckle Weeks, Max Brown and Anthony Howell.
