Stars Emily Blunt ("Young Victoria") and Jason Segel ("I Love You Man") are being lined up by Twentieth Century Fox to join funnyman Jack Black in his latest film, "Gulliver's Travels".
However, scheduling conflicts with another of Blunt's projects, "Iron Man 2", could see her have to jettison the role of Black Widow in the superhero franchise, reports Variety.
"Gulliver's Travels" begins shooting in the UK in late March, while "Iron Man 2" starts in April in California.
Adapted from Jonathan Swift's novel, "Gulliver's Travels" sees a travel writer head to Bermuda only to wash up on Lilliput - an island of very little people.
The film is slated for summer 2010.
