Less than two weeks ago the Bodyguard and Game of Thrones star was 20-1 with the bookies in the race to be the next James Bond.
However Madden has now seen his odds slashed to an impressive 6-1 according to Coral.
A spokesman for the bookmakers said: “Richard Madden has proved during the BBC One drama Bodyguard that he has what it takes to be a future James Bond actor.
“And following a flurry of bets over the last few days, his odds have been slashed on becoming the next 007.”
Meanwhile Craig’s final outing, currently only known as Bond 25, is having big production problems.
With shooting set to start on December 3, it was announced recently that director Danny Boyle had stepped down over creative differences.
Rumours are circling he left because Craig and he disagreed on casting for Bond 25’s villain, but also that the incumbent actor wanted his 007 to die.
Bond 25 is set for release in October 2019, but may get delayed.
