Harrison Ford had been working the Australian press circuit ahead of the premier of Star Wars: The Force Awakens on December 16.
The actor surprised an IMAX theater full of fans by sneaking into an exclusive 10 minute preview of the upcoming movie at Sydney's Darling Harbour.
Fans were so engrossed by the preview that no one noticed Ford had slipped in until the end.
According to Australian publication BMag:
"At the conclusion of 10 breakneck minutes of footage from the notoriously secretive film, Ford stood up out of his seat, and 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."
He then turned to the crowd and in a jovial manner said:
"Let’s make a deal — don’t tell your friends what you’ve seen here today."
Later that day, Ford spent a long time posing for photos and signing autographs for the hoards of fans that filled the harbor, before participating in a Q&A with a fellow Star Wars alum, Kiwi actor Jay Laga'aia, on the Opera House forecourt.
This next Star Wars film, directed by J.J. Abrams, as opposed to the movies' original creator George Lucas, will premiere December 18 in the US.
But Harrison Ford reassures us that the franchise is in good hands:
"[He brings] His own sensibility, his own craft, his own understanding of what the original films were important for, and his own experience as a young person watching them,"
"He's very much a fan of the original films."
