The 49-year-old actor spoke to People ahead of the debut of his new film Jay and Silent Bob Reboot which features cameos by a slew of stars including Jason Mewes, Affleck, 47, and Matt Damon.
“It was everything,” Smith said of Affleck’s involvement in the film. “It allowed me to elevate the movie. Suddenly I could include a scene that didn’t exist prior to him being involved that is like one of my favorite scenes I’ve ever shot. It’s really probably the best scene in the movie.
