Jeremy Renner was offered the role of Dexter but he turned it down. He had just played the serial killer Jeffrey Dahmer in a film and told them, “I can’t do any other serial killer movies or TV shows.”
They had to change the way the victims were strapped to the table because the actors were suffocating in the plastic wrap. It may not matter if their characters can breathe, but in real life, they have to be able to!
In real life, Michael C. Hall married Jennifer Carpenter who played his sister in the show. The two met on set and married in 2008. They were divorced two years later and worked on the show together for another three years.
The writers of the show considered the storyline of Dexter getting caught by his colleagues. Scott Buck, the producer of the show told EW, “We toyed with that idea, but it felt off-point. The story was ultimately about Dexter’s personal journey.”
During filming, Michael C. Hall accidentally crashed Dexter’s speedboat, Slice of Life, into a pier. He caused $8,000 worth of damage but was not asked to pay for the damages because, well, he is Dexter of the show Dexter.
While most TV shows allow actors to go off script and improvise, the show runners for Dexter said no way. The actors were required to stick to the scripts and if they wanted to change or add any dialogue, it had to be approved by the show’s creator, James Manos, Jr.
According to devoted fans of the show, Dexter killed an estimated 134 people. The count includes the blood slides that he collects from victims as well as the many that he kills and doesn’t collect any blood from.
Michael C. Hall was diagnosed with cancer in the middle of filming the 4th season. He didn’t tell anyone on set until they wrapped that season. He began treatment the day after they wrapped the 4th season.
The liquid blood that they would use was a mixture made of maple syrup, food coloring, peppermint oil and dawn dish soap. The peppermint oil is used to keep bugs away from it and the dawn dish soap was used to help the blood wash out of clothes and the sets that it comes into contact with.
