Dexter is one of the most beloved television series of all time, and for good reason.

The show, which follows the life of Dexter Morgan (a forensic expert by day and vigilante serial killer by night), is rife with the most interesting behind-the-scenes facts, which even the biggest fans would not know about.

Here's a look at how the series came to life.

Most people don't know that during the filming of Dexter, lead actor Michael C. Hall was diagnosed with Hodgkin's lymphoma.

Despite this difficult personal battle, Hall continued to work on the show while undergoing treatment.

His dedication to his role as Dexter Morgan is commendable and adds another layer of depth to his performance throughout the series.

The role of Miami in filming

Although Dexter is set in Miami, most of the filming was done in Los Angeles due to logistics.

However, establishing shots were filmed in Miami to keep it authentic for viewers.

This mixed bag of locations helped establish the vibrant yet gritty atmosphere that became synonymous with Dexter's world.

The iconic opening sequence

The iconic opening sequence of Dexter is memorable for making mundane morning activities eerily captivating, courtesy of its brilliant cinematography and sound design.

It was crafted with such precision to reflect Dexter Morgan's double life.

On the surface, he looks normal, but he harbors a far more sinister side.

This artistic decision perfectly establishes the mood of the show, emphasizing the lead's complicated personality from the get-go.

C. Hall and Jennifer Carpenter, who played adoptive siblings Dexter and Debra Morgan on Dexter, shared an unexpected off-screen romance.

The two secretly married in 2008, even as their characters's relationship took a complicated turn in the series.

Though the couple divorced in 2010, they remained friends and ensured their personal split didn't interfere with their on-screen chemistry, keeping their professional dynamic smooth until the show's end.

Influence from real-life forensics experts

To ensure the portrayal of forensic science was as close to reality as possible on-screen, Dexter consulted real-life forensic experts while making the show.

Their expertise influenced the portrayal of crime scene investigations in various episodes, making the show more authentic.

This ensured the forensic details were credible and part of the storytelling, engaging audiences with a realistic representation of crime-solving procedures without overshadowing the narrative's flow.
