8. Keanu Reeves - John Constantine
The star of Vertigo Comics' Hellblazer series - John Constantine is from Liverpool, England and is drawn to look like former Police frontman Sting. When Hellblazer was adapted to film as Constantine, Keanu Reeves was cast soon after his stint in The Matrix trilogy - leading some to believe the casting choice to be a gimmick to draw fans of that series to theatres. Sources close to the film's production, however, revealed that the look and Nationality of John Constantine were kept intact for early drafts of the film but there was no studio interest. The film quickly gained attention when the lead was changed to a dark haired American - much to the chagrin and outrage of Hellblazer fans.
