Fans of FlashForward plan to stage a blackout to protest the show's recent cancelation.
Members of a FlashForward fan group will gather in front of ABC offices in New York, Los Angeles, Chicago, Detroit and Atlanta on June 10. They are to mimic falling unconscious for two minutes and 17 seconds, just as in the programme's pilot episode.
Overseas supporters will join in the protest in London.
The group, which started the website PreventTheBlackout, has also shipped 20,000 "friendship bracelets", an item seen on the show, to the president of ABC.
