Olympic organizers want Twitter to be used a lot during the Games, but there’s one event where they’re asking Twitter users to shut the hell up: rehearsals for the opening ceremony.

Director Danny Boyle asked the 60,000 guests who are attending the rehearsals not to share any secrets of the $40 million opening ceremony. The Slumdog Millionaire director is encouraging people to keep their lips shut with the hashtag #savethesurprise, which is splashed across the stadium’s screens.

The large crowd kept their tweets mostly spoiler-free, with more than 2,300 people using the hashtag, according to Topsy. #savethesurprise trended worldwide on Monday night.

While some rabble-rousers tweeted a few pictures from the event, most rehearsalgoers were happy to follow Boyle’s directions.

“Breathtaking. Can't put it into words. Spectacular, clever, charming, moving & awe inspiring. Made me so proud,” tweeted Christopher Golds. Another Twitter user said Friday night’s ceremonies will be “amazing” and “we will rock London 2012.”

Even hard-to-please members of Parliament tweeted praise about Boyle’s creation: “Danny Boyle is a genius with a wicked sense of humour,” tweeted Labour MP David Miliband.

Despite Boyle’s efforts, details of the opening ceremony, which is slated to air Friday night in the United States, have been leaking. The stadium is said to be transformed into an English countryside with cottages, royal oak trees and a water wheel. It will feature up to 10,000 actors and 100 animals.

UK’s The Sun tabloid revealed a schedule of the opening ceremonies, but we’d rather #savethesurprise and avoid Boyle’s wrath.
