When Knight and Day hit theaters in 2010, it didn’t make a huge splash. Critics were mixed, and it didn’t perform as expected at the box office. But over time, this action-comedy starring Tom Cruise and Cameron Diaz has become a fan favorite—and it’s easy to see why.

Tom Cruise and Cameron Diaz light up the screen together. Their on-screen chemistry is fun, natural, and believable. Instead of feeling forced, their romance develops smoothly. Audiences loved how well they played off each other, mixing flirtation with laughter and action.
Cruise brings charm and humor to his role as Roy Miller, while Diaz adds energy and wit as June Havens. Together, they create a duo that keeps you entertained from start to finish.

Both Cruise and Diaz did most of their own stunts, which brings a real sense of excitement to the action scenes. Whether they’re riding a motorcycle or escaping danger, it feels thrilling because the actors are actually doing it.
While Knight and Day looks like a regular spy romance on the surface, it’s actually a smart satire. The movie pokes fun at spy movie clichés and even at Cruise’s own tough-guy image. Roy Miller is a wild and unpredictable version of a super spy—almost like a cartoon character in a real-world setting.
This playful approach makes the film stand out from other action-romantic comedies. It’s not trying to be super serious—it’s just trying to have fun.
Knight and Day moves fast, switches locations often, and mixes action with humor in just the right doses. It's the kind of movie you can watch any time you want a feel-good escape. Director James Mangold keeps the pace light and the mood fun, making it perfect for a cozy night in.
Even though critics weren’t impressed back in 2010, Knight and Day has found new life thanks to streaming platforms. Viewers who missed it the first time around are discovering its charm, and many are calling it an underrated gem.
The film’s easygoing tone, memorable performances, and playful action make it stand out more than ever today.
One reason Knight and Day didn’t do well initially was its confusing marketing. Ads made it look like a standard action romance, not the self-aware comedy it really is. So people weren’t sure what to expect.
Some critics didn’t like the goofy tone or the simple plot—but those are exactly the things fans love today. It’s like a modern-day screwball comedy mixed with action, and that’s what makes it special.
