Bloom next starred opposite Keira Knightley and Johnny Depp in Pirates of the Caribbean: The Curse of the Black Pearl, which was a blockbuster hit during the summer of 2003. After the success of Pirates, Bloom next took to the screen as Paris, the man who effectively started the Trojan War, in the 2004 Spring blockbuster, Troy opposite Brad Pitt, Eric Bana and Peter O'Toole. He subsequently played the lead roles in Ridley Scott's Kingdom of Heaven and Cameron Crowe's Elizabethtown (both 2005). In 2006, Bloom starred in sequel Pirates of the Caribbean: Dead Man's Chest and in the independently made Haven, of which he was also executive producer. In the same year he was one of the guest stars in the sitcom Extras, in which he portrayed an exaggeratedly arrogant, narcissistic version of himself who had a great loathing for Johnny Depp (his co-star in Pirates of the Caribbean); Bloom pushed for Extras to go further by making his part unlikable, and contributed to the gag about him admiring Depp out of sheer jealousy, that Depp was far more talented than he was, not to mention rated higher than him on the 'top hottest' charts. Also in 2006, Bloom was the most searched male on Google News. As of May 2007, Bloom has appeared in four of the top 15 highest-grossing films of all time.
In 2004, he became a full member of SGI-UK (the UK branch of Soka Gakkai International), a lay Buddhist association affiliated with the teachings of Nichiren.
Bloom was named the twelfth most influential person in the UK in a 2004 poll of cultural experts conducted for the BBC. Bloom appeared in his home town of Canterbury on 13 July 2010, where he was presented with an honorary degree from the University of Kent at Canterbury Cathedral. For contributions to the film industry, Bloom was inducted into the Hollywood Walk of Fame on 2 April 2014. His motion pictures walk of fame star is located at 6927 Hollywood Boulevard.
