Gemma Arterton doesn't think she's very famous.
The actress will star in a new musical remake of hit film 'Made in Dagenham' in London's West End later this year, but she admits she fears no one will want to buy tickets as they won't know who she is.
She said: "I'm doing a new musical at the end of the year at the Adelphi [theatre], 'Made in Dagenham', and we've got to sell it out.
"I'm like, 'How are we gonna sell out, with all these musicals that are closing, when the tickets are so expensive, and the theatres are so big?'
"I'm not that famous! It's not like they've got Keira Knightley or Natalie Portman. I'm sure people will see my name on the poster and they'll say, 'Who's that?' "
The 28-year-old beauty also lamented on her continuous connection to James Bond film 'Quantum of Solace', despite branching out into the respected world of theatre.
She told Radio Times magazine: "Even when the reviews came out for 'The Duchess of Malfi', it was always, 'Bond girl tries to do theatre.' I didn't even have a big part in Bond! I'm proud of it, but it is a bit weird that it's always brought up."
Gemma admits she is worried about singing in her new musical role. She explained: "I can sing, but I'm not like Mariah Carey. And I can sing and act at the same time.
"I remember when I saw 'Les Miserables', I thought, 'Oh God!' That's 'X Factor'-type musical theatre. I love the proper, Sondheim-y kind of stuff."
