Smith's one of the most unforgettable roles as Agent J, who was attractive, silly, reckless, and emotional. However, the 51-year-old actor would have lost the opportunity to be in this alien sci-fi movie, if another television star would have not refused to play Agent J.

While today's generation might not be able to see David Schwimmer as a huge star but Friends' fans would surely recognize the star. The actor portrayed Dr. Ross Gellar's character on the sitcom that skyrocketed his success.

The 53-year-old actor was loved by the fans for being nerdy, goofy, and in love with Rachel's character played by Jennifer Aniston. After Friends went off-air, Schwimmer seems to never find his feet in the business.

Comparing with his love interest on the show, Aniston who achieved great success. She went on to sign several movies and most of them were box office hits.

Men in Black was a huge box office success as it has a great screenplay and story. Smith's comic timing was cherry on the top for the fans. Now, it is difficult to see anyone else playing Agent J.

In fact, the actor got legendary status after the movie and fans almost forgot that he was a part of The Fresh Prince of Bel-Air sitcom. It is interesting that the role was first offered to the 90s star, Schwimmer.

According to Collider, in the late 90s, the actor was at the peak of his career as Friends made him a household name. However, the reasons have never been disclosed why Schwimmer rejected the role.

The actor is still known for his portrayal as Ross in Friends while he worked in several movies and series post the sitcom went off-air in 2004. Although it is hard to imagine anyone else playing Agent J in Men in Black, fans wonder how Schwimmer's career would have lifted if he agreed to do the role.

Probably, fans would have seen Schwimmer in films that are performed by Will Smith after Men in Black success such as Bad Boys, Gemini Man, or even The Pursuit of Happyness. However, Schwimmer will be seen with Nick Mohammed portraying an agent in Intelligence.
