In the prequel series, the two play Miami Metro Police Department officers. Patrick Dempsey and Sarah Michelle Gellar are prepared to take on the Dexter universe.

In an Instagram post published by Gellar on Monday, September 16, the two actors—who will be featured in the prequel series Dexter: Original Sin—teased their next TV project.
Gellar and Dempsey are dressed up in their amusing selfie. In the Paramount+ and Showtime series, the 58-year-old former cast member of Grey’s Anatomy plays Captain Aaron Spencer of Miami Metro Homicide.

The 47-year-old star of Buffy the Vampire Slayer, meantime, is appearing as a special guest as Tanya Martin, the Miami Metro Police Department’s chief of CSI and Dexter’s new supervisor at a forensics internship.
Referring to their previous successful concerts, Gellar captioned the photo, «The crossover you didn’t know you needed (#McBuff?!?)» For seven seasons, from 1997 to 2003, Gellar portrayed the young vampire slayer Buffy Summers on the television series Buffy.

From 2005 until 2015, Dempsey featured in the first 11 seasons of Grey’s Anatomy as Dr. Derek «McDreamy» Shepherd. The pair’s Scream franchise appearances drew criticism from several fans. One user said, «I would say Scream 2 meets Scream 3.»
In Scream 2 (1997), Gellar played Cici Cooper, and in Scream 3 (2000), Dempsey played Detective Mark Kincaid. Christian Slater plays Dexter Morgan’s father, Harry, while Patrick Gibson plays Dexter Morgan in Dexter: Original Sin.
