The Brit, who has portrayed loyal robot C-3Po in six Star Wars films, appeared at the New York Comic Con event recently to host a spotlight panel, and after insisting he would not be divulging any new Star Wars: Episode Vii secrets, he gave up a clumsy spoiler.
Explaining that movie bosses at Disney, the studio behind the latest sequel, have "very big ears", Daniels told film fans he could say nothing about the latest project in the franchise.
But when one devotee asked him what it was like to appear in all the Star Wars films, Daniels said, "Yes, I am the only actor to be in all seven because I feel..." Daniels quickly backtracked and spluttered out, "Six! Whatever."
There have been countless casting rumours about the film in recent weeks and both Michael B. Jordan and Irish actress Saoirse Ronan have confirmed they have auditioned for roles in the new Star Wars sequel.
