The Force — and the surprise — is strong with this one.

Harrison Ford sneaked into an Australian fan event for “Star Wars: The Force Awakens,” and almost went unnoticed, according to Australian outlet Bmag.

An already exciting event for fans, a select group of Australians were treated to ten minutes of the upcoming sequel at the IMAX Theatre at Sydney’s Darling Harbour. Little did they know that Han Solo himself was among them.

Ford managed to stay hidden throughout most of the event, sneaking in during the preview, and once it was over, he “stood up out of his seat,” says the report. “As if by magic, a spotlight hit the actor, who promised the audience that there was plenty more where that came from, and asked us to keep our lips sealed.”

“Let’s make a deal – don’t tell your friends what you’ve seen here today,” Ford told the audience.

The plot of “Star Wars: The Force Awakens” has been kept largely under wraps, with even trailers and marketing material revealing little of the wildly anticipated movie. Still, the cast, including Carrie Fisher, Daisy Ridley and John Boyega, along with Ford, has been busy on the press tour in the past few weeks.
