If you were one of the many people who saw “Fast & Furious Presents: Hobbs & Shaw” this weekend (and, judging by the box office numbers, you probably did), you were in for a few very big surprises. We spoke with the film’s director, David Leitch, about those surprises, which you can read about here.

And oh yeah – MASSIVE SPOILER WARNING!!!

So, what we’re talking about is that Ryan Reynolds, Detective Pikachu himself, shows up early in the movie as a governmental liaison who sets up the deal for Hobbs (Dwayne Johnson) to team up with Shaw (Jason Statham). Another big surprise comes later in the movie, when Johnson’s “Jumanji: The Next Level” co-star Kevin Hart shows up as an air marshal looking to help.

These are major movie stars appearing in a giant summer movie who appear for more than just a brief cameo. The fact that none of this leaked before the movie opened is kind of a miracle. And it sounds like there was a concerted effort by the filmmakers and marketing pros to keep it secret.

“We've all been really diligent to keep it under wraps and again, you're posting this after, so hopefully, fingers crossed, we've achieved it,” Leitch said. “I think you can see how important it is to the audience's experience of it. Again, I'm sure the cat will be out of the bag opening weekend but that first time is really fun.” Leitch added: “As a filmmaker I really wanted to preserve that for the audience. So hopefully we can do it.”

And if it seemed like Reynolds and Hart were introduced for a specific reason, well, you weren’t wrong. Although Leitch says that a conversation about the stars returning for future installments has “never been a conversation with the studio,” Leitch said it was always his “intention.” “I wanted to lay the groundwork for something fun and big and opportunities for everyone in the film to do something beyond it in this universe,” Leitch said. “So if those guys want to come back and play, I'm sure the studio would love to have them and that's how I intended to set them up.”

Again, given the box office (and the various plot threads established in this movie), chances are high that Hobbs and Shaw will ride again.
