Transformers: Dark of the Moon kicked off the Moscow Film Festival with a huge world premiere, featuring all the stars of the film and a special performance by Linkin Park.
"It's the biggest premiere in the history of Paramount. Probably one of the biggest premieres of all time," says franchise star Shia LaBeouf.
It was also an extra special moment for LaBeouf who has spent many years on this film.
"I spent all of my college years doing these movies, so this kind of like graduation."
And what a graduation party!
The huge premiere was presented in front of hundreds of fans in Moscow's famous Red Square, which was home to the Enemy Headquarters in the film.
The excitement in the air was absolutely palpable and all the stars were on-hand to enjoy the larger-than-life party, including Shia LaBoeuf, Rosie Huntington-Whiteley, Josh Duhamel, Patrick Dempsey, and Markiss McFadden.
Patrick Dempsey put into words what most of the cast was probably thinking as they looked out at all the cheering fans.
"Being a part of a movie this size? It's a fun ride."
