Actress Gemma Arterton doesn't think she is famous enough to sell out a theatre run on her own.

The 28-year-old 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.

`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?'` contactmusic.com quoted her as saying.

"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?'` she added.
