Controversial filmmaker Michael Moore has defended his new documentary Sicko from claims foreign distributors aren't interested. The movie, which takes aim at America's healthcare system, has so far failed to attract bids in the U.K. Industry insiders suggest poor box office takings and mixed reviews in the U.S. could be to blame.

However, Moore insists he's not worried by Britain's apparent apathy, declaring it's still too early to write off his film completely. A spokesman says, "Sometimes these things can take a little time. All I can say is watch this space."

Sicko has already been snapped up in many other European countries and non-English-speaking nations, including Japan.
