Brendan Gleeson Is Mocked By A Tennis Ball In New 'Mr. Mercedes' Teaser

To many, the worst part of tennis is just those tiny shorts you have to wear, but in the case of the upcoming TV series Mr. Mercedes, a tennis ball holds a far more nefarious meaning. Check out the all-new teaser for the show above.

In the teaser, a former detective (Brendan Gleeson) investigates a mysterious tennis ball he finds in his yard with a slyly grinning face on it, as he looks around for the culprit. Clearly, someone is out to make the detective's life a living hell through a series of bizarre clues that will torment him.

We recently got our first look at the upcoming Stephen King adaptation in the form of a behind-the-scenes featurette, but this is the first official teaser of what to expect in the series.

In the featurette, executive producer/director Jack Bender explained, "I wanted a show that was haunting and beautiful, without being style over substance, because the substance of this show are the characters."

The director added, "It's Stephen King writing about the monsters inside the people. it gets pretty dark and out there."
